ranjuvs26 Posted December 16, 2011 Share Posted December 16, 2011 Hi All, Am trying to decrypt a key encrypted by Java Triple DES function using PHP mcrypt function but with no luck. Find below the java code package com.wipro; import javax.crypto.Cipher; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.SecretKeySpec; public class Encrypt3DES { private byte[] key; private byte[] initializationVector; public Encrypt3DES(){ } public String encryptText(String plainText, String key) throws Exception{ //---- Use specified 3DES key and IV from other source -------------- byte[] plaintext = plainText.getBytes(); byte[] myIV = key.getBytes(); byte[] tdesKeyData = {(byte)0xA2, (byte)0x15, (byte)0x37, (byte)0x08, (byte)0xCA, (byte)0x62, (byte)0xC1, (byte)0xD2, (byte)0xF7, (byte)0xF1, (byte)0x93, (byte)0xDF, (byte)0xD2, (byte)0x15, (byte)0x4F, (byte)0x79, (byte)0x06, (byte)0x67, (byte)0x7A, (byte)0x82, (byte)0x94, (byte)0x16, (byte)0x32, (byte)0x95}; Cipher c3des = Cipher.getInstance("DESede/CBC/PKCS5Padding"); SecretKeySpec myKey = new SecretKeySpec(tdesKeyData, "DESede"); IvParameterSpec ivspec = new IvParameterSpec(myIV); c3des.init(Cipher.ENCRYPT_MODE, myKey, ivspec); byte[] cipherText = c3des.doFinal(plaintext); sun.misc.BASE64Encoder obj64=new sun.misc.BASE64Encoder(); return obj64.encode(cipherText); } public String decryptText(String encryptText, String key) throws Exception{ byte[] initializationVector = key.getBytes(); byte[] tdesKeyData = {(byte)0xA2, (byte)0x15, (byte)0x37, (byte)0x08, (byte)0xCA, (byte)0x62, (byte)0xC1, (byte)0xD2, (byte)0xF7, (byte)0xF1, (byte)0x93, (byte)0xDF, (byte)0xD2, (byte)0x15, (byte)0x4F, (byte)0x79, (byte)0x06, (byte)0x67, (byte)0x7A, (byte)0x82, (byte)0x94, (byte)0x16, (byte)0x32, (byte)0x95}; byte[] encData = new sun.misc.BASE64Decoder().decodeBuffer(encryptText); Cipher decipher = Cipher.getInstance("DESede/CBC/PKCS5Padding"); SecretKeySpec myKey = new SecretKeySpec(tdesKeyData, "DESede"); IvParameterSpec ivspec = new IvParameterSpec(initializationVector); decipher.init(Cipher.DECRYPT_MODE, myKey, ivspec); byte[] plainText = decipher.doFinal(encData); return new String(plainText); } } Kindly help me find out an equivalent PHP code to decrypt.
