NAME
DSA_size, DSA_bits, DSA_security_bits - get DSA signature size, key bits or security bits
SYNOPSIS
#include <openssl/dsa.h>
int DSA_bits(const DSA *dsa);
Deprecated since OpenSSL 3.0, can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see int DSA_size(const DSA *dsa);
int DSA_security_bits(const DSA *dsa);
DSA_bits() returns the number of bits in key dsa: this is the number of bits in the p parameter. The remaining functions described on this page are deprecated. Applications should instead use EVP_PKEY_size(3). 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_security_bits() returns the number of security bits of the given dsa key. See RETURN VALUES
DSA_bits() returns the number of bits in the key. DSA_size() returns the signature size in bytes. EVP_PKEY_security_bits(3), DSA_new(3), HISTORY
