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 encoded signature for key dsa in bytes. It can be used to determine how much memory must be allocated for a signature.

dsa->q must not be

.

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.
