openssl_get_md_methods

(PHP 5 >= 5.3.0)

openssl_get_md_methodsGets available digest methods

Description

array openssl_get_md_methods ([ bool $aliases = false ] )

Gets a list of available digest methods.

Parameters

aliases

Set to TRUE if digest aliases should be included within the returned array.

Return Values

An array of available digest methods.

Examples

Example #1 openssl_get_md_methods() example

Shows how the available digests might look, and also which aliases might be available.

<?php
$digests             
openssl_get_md_methods();
$digests_and_aliases openssl_get_md_methods(true);
$digest_aliases      array_diff($digests_and_aliases$digests);

print_r($digests);

print_r($digest_aliases);

?>

The above example will output something similar to:

 Array (  [0] => DSA  [1] => DSA-SHA  [2] => MD2  [3] => MD4  [4] => MD5  [5] => RIPEMD160  [6] => SHA  [7] => SHA1  [8] => SHA224  [9] => SHA256  [10] => SHA384  [11] => SHA512  [12] => dsaEncryption  [13] => dsaWithSHA  [14] => ecdsa-with-SHA1  [15] => md2  [16] => md4  [17] => md5  [18] => ripemd160  [19] => sha  [20] => sha1  [21] => sha224  [22] => sha256  [23] => sha384  [24] => sha512 ) Array (  [2] => DSA-SHA1  [3] => DSA-SHA1-old  [4] => DSS1  [9] => RSA-MD2  [10] => RSA-MD4  [11] => RSA-MD5  [12] => RSA-RIPEMD160  [13] => RSA-SHA  [14] => RSA-SHA1  [15] => RSA-SHA1-2  [16] => RSA-SHA224  [17] => RSA-SHA256  [18] => RSA-SHA384  [19] => RSA-SHA512  [28] => dsaWithSHA1  [29] => dss1  [32] => md2WithRSAEncryption  [34] => md4WithRSAEncryption  [36] => md5WithRSAEncryption  [37] => ripemd  [39] => ripemd160WithRSA  [40] => rmd160  [43] => sha1WithRSAEncryption  [45] => sha224WithRSAEncryption  [47] => sha256WithRSAEncryption  [49] => sha384WithRSAEncryption  [51] => sha512WithRSAEncryption  [52] => shaWithRSAEncryption  [53] => ssl2-md5  [54] => ssl3-md5  [55] => ssl3-sha1 )
