NAME

       DSA_size, DSA_bits - get DSA signature size or key bits

SYNOPSIS

        #include <openssl/dsa.h>

        int DSA_size(const DSA *dsa);
        int DSA_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.

RETURN VALUE

       DSA_size() returns the size in bytes.

       DSA_bits() returns the number of bits in the key.
