NAME

6       DSA_size, DSA_bits, DSA_security_bits - get DSA signature size, key
7       bits or security bits
8

SYNOPSIS

10        #include <openssl/dsa.h>
11
12        int DSA_size(const DSA *dsa);
13        int DSA_bits(const DSA *dsa);
14        int DSA_security_bits(const DSA *dsa);
15

DESCRIPTION

17       DSA_size() returns the maximum size of an ASN.1 encoded DSA signature
18       for key dsa in bytes. It can be used to determine how much memory must
19       be allocated for a DSA signature.
20
21       dsa->q must not be NULL.
22
23       DSA_bits() returns the number of bits in key dsa: this is the number of
24       bits in the p parameter.
25
26       DSA_security_bits() returns the number of security bits of the given
27       dsa key. See BN_security_bits(3).
28

RETURN VALUES

30       DSA_size() returns the signature size in bytes.
31
32       DSA_bits() returns the number of bits in the key.
