OPENSSL_ALGO_DSS1 (integer)

OPENSSL_ALGO_SHA1 (integer)

Used as default algorithm by openssl_sign() and openssl_verify().

OPENSSL_ALGO_SHA224 (integer)

OPENSSL_ALGO_SHA256 (integer)

OPENSSL_ALGO_SHA384 (integer)

OPENSSL_ALGO_SHA512 (integer)

OPENSSL_ALGO_RMD160 (integer)

OPENSSL_ALGO_MD5 (integer)

OPENSSL_ALGO_MD4 (integer)

OPENSSL_ALGO_MD2 (integer)

As of PHP 5.2.13 and PHP 5.3.2, this constant is only available if PHP is compiled with MD2 support. This requires passing in the -DHAVE_OPENSSL_MD2_H CFLAG when compiling PHP, and enable-md2 when compiling OpenSSL 1.0.0+.

Notă:

These constants were added in 5.0.0.

OPENSSL_ALGO_MD2, OPENSSL_ALGO_MD4, OPENSSL_ALGO_MD5, OPENSSL_ALGO_SHA1, OPENSSL_ALGO_DSS1

Notă:

These constants were added in 5.4.8.

OPENSSL_ALGO_RMD160, OPENSSL_ALGO_SHA224, OPENSSL_ALGO_SHA256, OPENSSL_ALGO_SHA384, OPENSSL_ALGO_SHA512
