DSA_SIZE(3)                         OpenSSL                        DSA_SIZE(3)
NAME
       DSA_size, DSA_bits, DSA_security_bits - get DSA signature size, key
       bits or security bits
SYNOPSIS
        #include <openssl/dsa.h>
        int DSA_size(const DSA *dsa);
        int DSA_bits(const DSA *dsa);
        int DSA_security_bits(const DSA *dsa);
DESCRIPTION
       DSA_size() returns the maximum size of an ASN.1 encoded DSA signature
       for key dsa in bytes. It can be used to determine how much memory must
       be allocated for a DSA signature.
       dsa->q must not be NULL.
       DSA_bits() returns the number of bits in key dsa: this is the number of
       bits in the p parameter.
       DSA_security_bits() returns the number of security bits of the given
       dsa key. See BN_security_bits(3).
RETURN VALUES
       DSA_size() returns the signature size in bytes.
       DSA_bits() returns the number of bits in the key.
