openssl_err(3) -- error codes
|
|
When a call to the OpenSSL library fails, this is usually signalled by the return value, and an error code is stored in an error queue associated with the current thread. The err library provides func... |
|
openssl_evp(3) -- high-level cryptographic functions
|
|
The EVP library provides a high-level interface to cryptographic functions. EVP_Seal... and EVP_Open... provide public key encryption and decryption to implement digital "envelopes". The EVP_Sign...... |

openssl_hmac(3) -- HMAC message authentication code
|
|
HMAC is a MAC (message authentication code), i.e. a keyed hash function used for message authentication, which is based on a hash function. HMAC() computes the message authentication code of the n byt... |
|
openssl_lhash(3) -- dynamic hash table
|
|
This library implements dynamic hash tables. The hash table entries can be arbitrary structures. Usually they consist of key and value fields. lh_new() creates a new LHASH structure. hash takes a poin... |
|
openssl_md5(3) -- MD2, MD4, and MD5 hash functions
|
|
MD2, MD4, and MD5 are cryptographic hash functions with a 128 bit output. MD2(), MD4(), and MD5() compute the MD2, MD4, and MD5 message digest of the n bytes at d and place it in md (which must have s... |
|
openssl_mdc2(3) -- MDC2 hash function
|
|
MDC2 is a method to construct hash functions with 128 bit output from block ciphers. These functions are an implementation of MDC2 with DES. MDC2() computes the MDC2 message digest of the n bytes at d... |
|
openssl_rand(3) -- pseudo-random number generator
|
|
These functions implement a cryptographically secure pseudo-random number generator (PRNG). It is used by other library functions for example to generate random keys, and applications can use it when ... |
|
openssl_rc4(3) -- RC4 encryption
|
|
This library implements the Alleged RC4 cipher, which is described for example in Applied Cryptography. It is believed to be compatible with RC4[TM], a proprietary cipher of RSA Security Inc. RC4 is a... |
|
openssl_ripemd(3) -- RIPEMD-160 hash function
|
|
RIPEMD-160 is a cryptographic hash function with a 160 bit output. RIPEMD160() computes the RIPEMD-160 message digest of the n bytes at d and places it in md (which must have space for RIPEMD160_DIGES... |
|
openssl_rsa(3) -- RSA public key cryptosystem
|
|
These functions implement RSA public key encryption and signatures as defined in PKCS #1 v2.0 [RFC 2437]. The RSA structure consists of several BIGNUM components. It can contain public as well as priv... |
|
openssl_sha(3) -- Secure Hash Algorithm
|
|
SHA-1 (Secure Hash Algorithm) is a cryptographic hash function with a 160 bit output. SHA1() computes the SHA-1 message digest of the n bytes at d and places it in md (which must have space for SHA_DI... |
|
openssl_threads(3) -- OpenSSL thread support
|
|
OpenSSL can safely be used in multi-threaded applications provided that at least two callback functions are set. locking_function(int mode, int n, const char *file, int line) is needed to perform lock... |
|
OPENSSL_VERSION_NUMBER(3) -- get OpenSSL version number
|
|
OPENSSL_VERSION_NUMBER is a numeric release version identifier: MMNNFFPPS: major minor fix patch status The status nibble has one of the values 0 for development, 1 to e for betas 1 to 14, and f for r... |
|
orcmd(3) -- routines for returning a stream to a remote command
|
|
The rcmd() function is available for use by anyone to run commands on a remote system. It acts like the orcmd() command, with the exception that it makes a call out to the rcmd(1) command, or any othe... |
|
orcmd_af(3) -- routines for returning a stream to a remote command
|
|
The rcmd() function is available for use by anyone to run commands on a remote system. It acts like the orcmd() command, with the exception that it makes a call out to the rcmd(1) command, or any othe... |
