PHP如何?可以與線上加密解密工具互動的des密碼編譯演算法

使用php做des加密,加密出來的密文,可以在des線上加密解密工具上解密出來

• 不同的加密方式可得出不同的結果可導致最終的資料並不通用儘管是同一個演算法

PHP內建DES和3DES的加解密

PHP自身支援的加密方式列表(依賴mcrypt)：http://cn2.php.net/manual/zh/mcrypt.ciph...

echo mcrypt_get_key_size(MCRYPT_DES,MCRYPT_MODE_CFB);// des cfb 秘鑰長度為8位// 秘鑰$key = 11111111;// 建立IV$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_DES, MCRYPT_MODE_CFB),MCRYPT_RAND);// 加密 使用CFB模式$data = mcrypt_encrypt(MCRYPT_DES, $key, '加密的資料', MCRYPT_MODE_CFB, $iv);var_dump($data);

另外PHP的OpenSSL擴充也可以直接用於加密 相關函數：openssl_encrypt

// 擷取OpenSSL支援的加密參數列表print_r(openssl_get_cipher_methods());Array(    [0] => AES-128-CBC    [1] => AES-128-CFB    [2] => AES-128-CFB1    [3] => AES-128-CFB8    [4] => AES-128-CTR    [5] => AES-128-ECB    [6] => AES-128-OFB    [7] => AES-128-XTS    [8] => AES-192-CBC    [9] => AES-192-CFB    [10] => AES-192-CFB1    [11] => AES-192-CFB8    [12] => AES-192-CTR    [13] => AES-192-ECB    [14] => AES-192-OFB    [15] => AES-256-CBC    [16] => AES-256-CFB    [17] => AES-256-CFB1    [18] => AES-256-CFB8    [19] => AES-256-CTR    [20] => AES-256-ECB    [21] => AES-256-OFB    [22] => AES-256-XTS    [23] => BF-CBC    [24] => BF-CFB    [25] => BF-ECB    [26] => BF-OFB    [27] => CAMELLIA-128-CBC    [28] => CAMELLIA-128-CFB    [29] => CAMELLIA-128-CFB1    [30] => CAMELLIA-128-CFB8    [31] => CAMELLIA-128-ECB    [32] => CAMELLIA-128-OFB    [33] => CAMELLIA-192-CBC    [34] => CAMELLIA-192-CFB    [35] => CAMELLIA-192-CFB1    [36] => CAMELLIA-192-CFB8    [37] => CAMELLIA-192-ECB    [38] => CAMELLIA-192-OFB    [39] => CAMELLIA-256-CBC    [40] => CAMELLIA-256-CFB    [41] => CAMELLIA-256-CFB1    [42] => CAMELLIA-256-CFB8    [43] => CAMELLIA-256-ECB    [44] => CAMELLIA-256-OFB    [45] => CAST5-CBC    [46] => CAST5-CFB    [47] => CAST5-ECB    [48] => CAST5-OFB    [49] => DES-CBC    [50] => DES-CFB    [51] => DES-CFB1    [52] => DES-CFB8    [53] => DES-ECB    [54] => DES-EDE    [55] => DES-EDE-CBC    [56] => DES-EDE-CFB    [57] => DES-EDE-OFB    [58] => DES-EDE3    [59] => DES-EDE3-CBC    [60] => DES-EDE3-CFB    [61] => DES-EDE3-CFB1    [62] => DES-EDE3-CFB8    [63] => DES-EDE3-OFB    [64] => DES-OFB    [65] => DESX-CBC    [66] => GOST 28147-89    [67] => IDEA-CBC    [68] => IDEA-CFB    [69] => IDEA-ECB    [70] => IDEA-OFB    [71] => RC2-40-CBC    [72] => RC2-64-CBC    [73] => RC2-CBC    [74] => RC2-CFB    [75] => RC2-ECB    [76] => RC2-OFB    [77] => RC4    [78] => RC4-40    [79] => RC4-HMAC-MD5    [80] => SEED-CBC    [81] => SEED-CFB    [82] => SEED-ECB    [83] => SEED-OFB    [84] => aes-128-cbc    [85] => aes-128-ccm    [86] => aes-128-cfb    [87] => aes-128-cfb1    [88] => aes-128-cfb8    [89] => aes-128-ctr    [90] => aes-128-ecb    [91] => aes-128-gcm    [92] => aes-128-ofb    [93] => aes-128-xts    [94] => aes-192-cbc    [95] => aes-192-ccm    [96] => aes-192-cfb    [97] => aes-192-cfb1    [98] => aes-192-cfb8    [99] => aes-192-ctr    [100] => aes-192-ecb    [101] => aes-192-gcm    [102] => aes-192-ofb    [103] => aes-256-cbc    [104] => aes-256-ccm    [105] => aes-256-cfb    [106] => aes-256-cfb1    [107] => aes-256-cfb8    [108] => aes-256-ctr    [109] => aes-256-ecb    [110] => aes-256-gcm    [111] => aes-256-ofb    [112] => aes-256-xts    [113] => bf-cbc    [114] => bf-cfb    [115] => bf-ecb    [116] => bf-ofb    [117] => camellia-128-cbc    [118] => camellia-128-cfb    [119] => camellia-128-cfb1    [120] => camellia-128-cfb8    [121] => camellia-128-ecb    [122] => camellia-128-ofb    [123] => camellia-192-cbc    [124] => camellia-192-cfb    [125] => camellia-192-cfb1    [126] => camellia-192-cfb8    [127] => camellia-192-ecb    [128] => camellia-192-ofb    [129] => camellia-256-cbc    [130] => camellia-256-cfb    [131] => camellia-256-cfb1    [132] => camellia-256-cfb8    [133] => camellia-256-ecb    [134] => camellia-256-ofb    [135] => cast5-cbc    [136] => cast5-cfb    [137] => cast5-ecb    [138] => cast5-ofb    [139] => des-cbc    [140] => des-cfb    [141] => des-cfb1    [142] => des-cfb8    [143] => des-ecb    [144] => des-ede    [145] => des-ede-cbc    [146] => des-ede-cfb    [147] => des-ede-ofb    [148] => des-ede3    [149] => des-ede3-cbc    [150] => des-ede3-cfb    [151] => des-ede3-cfb1    [152] => des-ede3-cfb8    [153] => des-ede3-ofb    [154] => des-ofb    [155] => desx-cbc    [156] => gost89    [157] => gost89-cnt    [158] => id-aes128-CCM    [159] => id-aes128-GCM    [160] => id-aes128-wrap    [161] => id-aes192-CCM    [162] => id-aes192-GCM    [163] => id-aes192-wrap    [164] => id-aes256-CCM    [165] => id-aes256-GCM    [166] => id-aes256-wrap    [167] => id-smime-alg-CMS3DESwrap    [168] => idea-cbc    [169] => idea-cfb    [170] => idea-ecb    [171] => idea-ofb    [172] => rc2-40-cbc    [173] => rc2-64-cbc    [174] => rc2-cbc    [175] => rc2-cfb    [176] => rc2-ecb    [177] => rc2-ofb    [178] => rc4    [179] => rc4-40    [180] => rc4-hmac-md5    [181] => seed-cbc    [182] => seed-cfb    [183] => seed-ecb    [184] => seed-ofb)

主要是des的演算法，然後是發送一個請求，返回結果而已。
網上應該有類似的演算法，推薦一個：

(百度搜尋，找到的)

跟其他語言互動的時候,對方語言直接先base64解密再進行des解密就可以獲得未經處理資料了.python,ios是可以,其他語言沒測試,即des_decrypt(base64_decrypt($pass_string))就可了
