OPENSSL_GET_CIPHER_METHODS(3) 1 OPENSSL_GET_CIPHER_METHODS(3) openssl_get_cipher_methods - Gets available cipher methods SYNOPSIS
array openssl_get_cipher_methods ([bool $aliases = false]) DESCRIPTION
Gets a list of available cipher methods. PARAMETERS
o $aliases - Set to TRUE if cipher aliases should be included within the returned array. RETURN VALUES
An array of available cipher methods. EXAMPLES
Example #1 openssl_get_cipher_methods(3) example Shows how the available ciphers might look, and also which aliases might be available. <?php $ciphers = openssl_get_cipher_methods(); $ciphers_and_aliases = openssl_get_cipher_methods(true); $cipher_aliases = array_diff($ciphers_and_aliases, $ciphers); print_r($ciphers); print_r($cipher_aliases); ?> The above example will output something similar to: Array ( [0] => AES-128-CBC [1] => AES-128-CFB [2] => AES-128-CFB1 [3] => AES-128-CFB8 [4] => AES-128-ECB [5] => AES-128-OFB [6] => AES-192-CBC [7] => AES-192-CFB [8] => AES-192-CFB1 [9] => AES-192-CFB8 [10] => AES-192-ECB [11] => AES-192-OFB [12] => AES-256-CBC [13] => AES-256-CFB [14] => AES-256-CFB1 [15] => AES-256-CFB8 [16] => AES-256-ECB [17] => AES-256-OFB [18] => BF-CBC [19] => BF-CFB [20] => BF-ECB [21] => BF-OFB [22] => CAST5-CBC [23] => CAST5-CFB [24] => CAST5-ECB [25] => CAST5-OFB [26] => DES-CBC [27] => DES-CFB [28] => DES-CFB1 [29] => DES-CFB8 [30] => DES-ECB [31] => DES-EDE [32] => DES-EDE-CBC [33] => DES-EDE-CFB [34] => DES-EDE-OFB [35] => DES-EDE3 [36] => DES-EDE3-CBC [37] => DES-EDE3-CFB [38] => DES-EDE3-OFB [39] => DES-OFB [40] => DESX-CBC [41] => IDEA-CBC [42] => IDEA-CFB [43] => IDEA-ECB [44] => IDEA-OFB [45] => RC2-40-CBC [46] => RC2-64-CBC [47] => RC2-CBC [48] => RC2-CFB [49] => RC2-ECB [50] => RC2-OFB [51] => RC4 [52] => RC4-40 [53] => aes-128-cbc [54] => aes-128-cfb [55] => aes-128-cfb1 [56] => aes-128-cfb8 [57] => aes-128-ecb [58] => aes-128-ofb [59] => aes-192-cbc [60] => aes-192-cfb [61] => aes-192-cfb1 [62] => aes-192-cfb8 [63] => aes-192-ecb [64] => aes-192-ofb [65] => aes-256-cbc [66] => aes-256-cfb [67] => aes-256-cfb1 [68] => aes-256-cfb8 [69] => aes-256-ecb [70] => aes-256-ofb [71] => bf-cbc [72] => bf-cfb [73] => bf-ecb [74] => bf-ofb [75] => cast5-cbc [76] => cast5-cfb [77] => cast5-ecb [78] => cast5-ofb [79] => des-cbc [80] => des-cfb [81] => des-cfb1 [82] => des-cfb8 [83] => des-ecb [84] => des-ede [85] => des-ede-cbc [86] => des-ede-cfb [87] => des-ede-ofb [88] => des-ede3 [89] => des-ede3-cbc [90] => des-ede3-cfb [91] => des-ede3-ofb [92] => des-ofb [93] => desx-cbc [94] => idea-cbc [95] => idea-cfb [96] => idea-ecb [97] => idea-ofb [98] => rc2-40-cbc [99] => rc2-64-cbc [100] => rc2-cbc [101] => rc2-cfb [102] => rc2-ecb [103] => rc2-ofb [104] => rc4 [105] => rc4-40 ) Array ( [18] => AES128 [19] => AES192 [20] => AES256 [21] => BF [26] => CAST [27] => CAST-cbc [32] => DES [47] => DES3 [48] => DESX [50] => IDEA [55] => RC2 [82] => aes128 [83] => aes192 [84] => aes256 [85] => bf [90] => blowfish [91] => cast [92] => cast-cbc [97] => des [112] => des3 [113] => desx [115] => idea [120] => rc2 ) SEE ALSO
