DESCRIPTION
       These functions are typically called after X509_verify_cert() has
       indicated an error or in a verification callback to determine the
       nature of an error.
       X509_STORE_CTX_get_error() returns the error code of ctx, see the ERROR
       CODES section for a full description of all error codes.
       X509_STORE_CTX_set_error() sets the error code of ctx to s. For example
       it might be used in a verification callback to set an error based on
       additional checks.
       X509_STORE_CTX_get_error_depth() returns the depth of the error. This
       is a non-negative integer representing where in the certificate chain
       the error occurred. If it is zero it occurred in the end entity
       certificate, one if it is the certificate which signed the end entity
       certificate and so on.
       X509_STORE_CTX_get_current_cert() returns the certificate in ctx which
       caused the error or NULL if no certificate is relevant.
       X509_STORE_CTX_get1_chain() returns a complete validate chain if a
       previous call to X509_verify_cert() is successful. If the call to
       X509_verify_cert() is not successful the returned chain may be
       incomplete or invalid. The returned chain persists after the ctx
       structure is freed, when it is no longer needed it should be free up
       using:
         sk_X509_pop_free(chain, X509_free);
       X509_verify_cert_error_string() returns a human readable error string
       for verification error n.
RETURN VALUES
       X509_STORE_CTX_get_error() returns X509_V_OK or an error code.
       X509_STORE_CTX_get_error_depth() returns a non-negative error depth.
       X509_STORE_CTX_get_current_cert() returns the cerificate which caused
       the error or NULL if no certificate is relevant to the error.
       X509_verify_cert_error_string() returns a human readable error string
       for verification error n.
ERROR CODES
       A list of error codes and messages is shown below.  Some of the error
       codes are defined but currently never returned: these are described as
       "unused".
       X509_V_OK: ok
           the operation was successful.
       X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT: unable to get issuer certificate
           the issuer certificate could not be found: this occurs if the
           issuer certificate of an untrusted certificate cannot be found.
       X509_V_ERR_UNABLE_TO_GET_CRL: unable to get certificate CRL
           the CRL of a certificate could not be found.
       X509_V_ERR_UNABLE_TO_DECRYPT_CERT_SIGNATURE: unable to decrypt
       certificate's signature
           the certificate signature could not be decrypted. This means that
           the actual signature value could not be determined rather than it
           not matching the expected value, this is only meaningful for RSA
           keys.
       X509_V_ERR_UNABLE_TO_DECRYPT_CRL_SIGNATURE: unable to decrypt CRL's
       signature
           the CRL signature could not be decrypted: this means that the
           actual signature value could not be determined rather than it not
           matching the expected value.  Unused.
       X509_V_ERR_UNABLE_TO_DECODE_ISSUER_PUBLIC_KEY: unable to decode issuer
       public key
           the public key in the certificate SubjectPublicKeyInfo could not be
           read.
       X509_V_ERR_CERT_SIGNATURE_FAILURE: certificate signature failure
           the signature of the certificate is invalid.
       X509_V_ERR_CRL_SIGNATURE_FAILURE: CRL signature failure
           the signature of the certificate is invalid.
       X509_V_ERR_CERT_NOT_YET_VALID: certificate is not yet valid
           the certificate is not yet valid: the notBefore date is after the
           current time.
       X509_V_ERR_CERT_HAS_EXPIRED: certificate has expired
           the certificate has expired: that is the notAfter date is before
           the current time.
       X509_V_ERR_CRL_NOT_YET_VALID: CRL is not yet valid
           the CRL is not yet valid.
       X509_V_ERR_CRL_HAS_EXPIRED: CRL has expired
           the CRL has expired.
       X509_V_ERR_ERROR_IN_CERT_NOT_BEFORE_FIELD: format error in
       certificate's notBefore field
           the certificate notBefore field contains an invalid time.
       X509_V_ERR_ERROR_IN_CERT_NOT_AFTER_FIELD: format error in certificate's
       notAfter field
           the certificate notAfter field contains an invalid time.
       X509_V_ERR_ERROR_IN_CRL_LAST_UPDATE_FIELD: format error in CRL's
       lastUpdate field
           the CRL lastUpdate field contains an invalid time.
       X509_V_ERR_ERROR_IN_CRL_NEXT_UPDATE_FIELD: format error in CRL's
       nextUpdate field
           the CRL nextUpdate field contains an invalid time.
       X509_V_ERR_OUT_OF_MEM: out of memory
           an error occurred trying to allocate memory. This should never
           happen.
       X509_V_ERR_DEPTH_ZERO_SELF_SIGNED_CERT: self signed certificate
           the passed certificate is self signed and the same certificate
           cannot be found in the list of trusted certificates.
       X509_V_ERR_SELF_SIGNED_CERT_IN_CHAIN: self signed certificate in
       certificate chain
           the certificate chain could be built up using the untrusted
           certificates but the root could not be found locally.
       X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY: unable to get local
       issuer certificate
           the issuer certificate of a locally looked up certificate could not
           be found.  This normally means the list of trusted certificates is
           not complete.
       X509_V_ERR_UNABLE_TO_VERIFY_LEAF_SIGNATURE: unable to verify the first
       certificate
           no signatures could be verified because the chain contains only one
           certificate and it is not self signed.
       X509_V_ERR_CERT_CHAIN_TOO_LONG: certificate chain too long
           the certificate chain length is greater than the supplied maximum
           depth. Unused.
       X509_V_ERR_CERT_REVOKED: certificate revoked
           the certificate has been revoked.
       X509_V_ERR_INVALID_CA: invalid CA certificate
           a CA certificate is invalid. Either it is not a CA or its
           extensions are not consistent with the supplied purpose.
       X509_V_ERR_PATH_LENGTH_EXCEEDED: path length constraint exceeded
           the basicConstraints pathlength parameter has been exceeded.
       X509_V_ERR_INVALID_PURPOSE: unsupported certificate purpose
           the supplied certificate cannot be used for the specified purpose.
       X509_V_ERR_CERT_UNTRUSTED: certificate not trusted
           the root CA is not marked as trusted for the specified purpose.
       X509_V_ERR_CERT_REJECTED: certificate rejected
           the root CA is marked to reject the specified purpose.
       X509_V_ERR_SUBJECT_ISSUER_MISMATCH: subject issuer mismatch
           the current candidate issuer certificate was rejected because its
           subject name did not match the issuer name of the current
           certificate. This is only set if issuer check debugging is enabled
           it is used for status notification and is not in itself an error.
       X509_V_ERR_AKID_SKID_MISMATCH: authority and subject key identifier
       mismatch
           the current candidate issuer certificate was rejected because its
           subject key identifier was present and did not match the authority
           key identifier current certificate. This is only set if issuer
           check debugging is enabled it is used for status notification and
           is not in itself an error.
       X509_V_ERR_AKID_ISSUER_SERIAL_MISMATCH: authority and issuer serial
       number mismatch
           the current candidate issuer certificate was rejected because its
           issuer name and serial number was present and did not match the
           authority key identifier of the current certificate. This is only
           set if issuer check debugging is enabled it is used for status
           notification and is not in itself an error.
       X509_V_ERR_KEYUSAGE_NO_CERTSIGN:key usage does not include certificate
       signing
           the current candidate issuer certificate was rejected because its
           keyUsage extension does not permit certificate signing. This is
           only set if issuer check debugging is enabled it is used for status
           notification and is not in itself an error.
       X509_V_ERR_INVALID_EXTENSION: invalid or inconsistent certificate
       extension
           A certificate extension had an invalid value (for example an
           incorrect encoding) or some value inconsistent with other
           extensions.
       X509_V_ERR_INVALID_POLICY_EXTENSION: invalid or inconsistent
       certificate policy extension
           A certificate policies extension had an invalid value (for example
           an incorrect encoding) or some value inconsistent with other
           extensions. This error only occurs if policy processing is enabled.
       X509_V_ERR_NO_EXPLICIT_POLICY: no explicit policy
           The verification flags were set to require and explicit policy but
           none was present.
       X509_V_ERR_DIFFERENT_CRL_SCOPE: Different CRL scope
           The only CRLs that could be found did not match the scope of the
           certificate.
       X509_V_ERR_UNSUPPORTED_EXTENSION_FEATURE: Unsupported extension feature
           Some feature of a certificate extension is not supported. Unused.
       X509_V_ERR_PERMITTED_VIOLATION: permitted subtree violation
           A name constraint violation occurred in the permitted subtrees.
       X509_V_ERR_EXCLUDED_VIOLATION: excluded subtree violation
           A name constraint violation occurred in the excluded subtrees.
       X509_V_ERR_SUBTREE_MINMAX: name constraints minimum and maximum not
       supported
           A certificate name constraints extension included a minimum or
           maximum field: this is not supported.
       X509_V_ERR_UNSUPPORTED_CONSTRAINT_TYPE: unsupported name constraint
       type
           An unsupported name constraint type was encountered. OpenSSL
           currently only supports directory name, DNS name, email and URI
           types.
       X509_V_ERR_UNSUPPORTED_CONSTRAINT_SYNTAX: unsupported or invalid name
       constraint syntax
           The format of the name constraint is not recognised: for example an
           email address format of a form not mentioned in RFC3280. This could
           be caused by a garbage extension or some new feature not currently
           supported.
       X509_V_ERR_CRL_PATH_VALIDATION_ERROR: CRL path validation error
           An error occurred when attempting to verify the CRL path. This
           error can only happen if extended CRL checking is enabled.
       X509_V_ERR_APPLICATION_VERIFICATION: application verification failure
           an application specific error. This will never be returned unless
           explicitly set by an application.
NOTES
       The above functions should be used instead of directly referencing the
       fields in the X509_VERIFY_CTX structure.
       In versions of OpenSSL before 1.0 the current certificate returned by
       X509_STORE_CTX_get_current_cert() was never NULL. Applications should
       check the return value before printing out any debugging information
       relating to the current certificate.
       If an unrecognised error code is passed to
       X509_verify_cert_error_string() the numerical value of the unknown code
       is returned in a static buffer. This is not thread safe but will never
       happen unless an invalid code is passed.
