=pod =head1 NAME BN_security_bits - returns bits of security based on given numbers =head1 SYNOPSIS #include <openssl/bn.h> int BN_security_bits(int L, int N); =head1 DESCRIPTION BN_security_bits() returns the number of bits of security provided by a specific algorithm and a particular key size. The bits of security is defined in NIST SP800-57. Currently, BN_security_bits() support two types of asymmetric algorithms: the FFC (Finite Field Cryptography) and IFC (Integer Factorization Cryptography). For FFC, e.g., DSA and DH, both parameters B<L> and B<N> are used to decide the bits of security, where B<L> is the size of the public key and B<N> is the size of the private key. For IFC, e.g., RSA, only B<L> is used and it's commonly considered to be the key size (modulus). =head1 RETURN VALUES Number of security bits. =head1 NOTES ECC (Elliptic Curve Cryptography) is not covered by the BN_security_bits() function. The symmetric algorithms are not covered neither. =head1 SEE ALSO L<DH_security_bits(3)>, L<DSA_security_bits(3)>, L<RSA_security_bits(3)> =head1 HISTORY The BN_security_bits() function was added in OpenSSL 1.1.0. =head1 COPYRIGHT Copyright 2017-2019 The OpenSSL Project Authors.
