NAME

crypto - OpenSSL cryptographic library

SYNOPSIS

DESCRIPTION

The OpenSSL crypto library implements a wide range of cryptographic algorithms used in various Internet standards. The services provided by this library are used by the OpenSSL implementations of SSL, TLS and S/MIME, and they have also been used to implement SSH, OpenPGP, and other cryptographic standards.

OVERVIEW

libcrypto consists of a number of sub-libraries that implement the individual algorithms.

The functionality includes symmetric encryption, public key cryptography and key agreement, certificate handling, cryptographic hash functions and a cryptographic pseudo-random number generator.

SYMMETRIC CIPHERS: blowfish(3), cast(3), des(3), idea(3), rc2(3), rc4(3), rc5(3)
PUBLIC KEY CRYPTOGRAPHY AND KEY AGREEMENT: dsa(3), dh(3), rsa(3)
CERTIFICATES: x509(3), x509v3(3)
AUTHENTICATION CODES, HASH FUNCTIONS: hmac(3), md2(3), md4(3), md5(3), mdc2(3), ripemd(3), sha(3)
AUXILIARY FUNCTIONS: err(3), threads(3), rand(3)
INPUT/OUTPUT, DATA ENCODING: asn1(3), bio(3), evp(3), pem(3), pkcs7(3), pkcs12(3)
INTERNAL FUNCTIONS: bn(3), buffer(3), lhash(3), objects(3), stack(3), txt_db(3)
