Node.js解密不适用于其他密码的密文

本文介绍了Node.js解密不适用于其他密码的密文的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我使用javax.crypto.Cipher org.apachemons.codec.binary.Base64创建了密文，并使用Java，如下所示：

import java.security.NoSuchAlgorithmException; import java.security.NoSuchProviderException; import javax.crypto.Cipher; import javax.crypto.NoSuchPaddingException; import javax.crypto.SecretKey; import javax.crypto.spec.SecretKeySpec; import org.apachemons.codec.binary.Base64; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public final class PwdCipher { private static final Logger LOG = LoggerFactory.getLogger（PwdCipher.class）; private static final int BASE64_ARG0 = 32; private static final String SECRET =tvnw63ufg9gh5392; private static byte [] linebreak = {}; private static SecretKey key; 私有静态密码密码; 私有静态Base64编码器; static { key = new SecretKeySpec（SECRET.getBytes（），AES）; try { cipher = Cipher.getInstance（AES / ECB / PKCS5Padding，SunJCE）; } catch（NoSuchAlgorithmException | NoSuchProviderException | NoSuchPaddingException e）{ LOG.debug（Erro ao criar encriptador，e）; } coder = new Base64（BASE64_ARG0，linebreak，true）; } 私人PwdCipher（）{} public static synchronized String encrypt（String plainText）{ try { cipher.init（Cipher.ENCRYPT_MODE，key）; byte [] cipherText = cipher.doFinal（plainText.getBytes（））; return new String（coder.encode（cipherText））; } catch（Exception e）{ throw new GdocException（Erro ao encriptar senha。，e）; } } public static synchronized String decrypt（String codedText）{ try { byte [] encypted = coder.decode（codedText.getBytes （））; cipher.init（Cipher.DECRYPT_MODE，key）; byte [] decryptpted = cipher.doFinal（encypted）; return new String（decryptpted）; } catch（Exception e）{ throw new GdocException（Erro ao decriptar senha。，e）; } } }

我需要使用Node.js解密文本（用PwdCipher类加密），但是当我使用以下代码时：

exports.decryptLdapPassword = function（password）{ var key ='tvnw63ufg9gh5392'; var ciphertext = password; var crypto = require（'crypto'）; var decipher = crypto.createDecipher（'aes-128-ecb'，key）; var decryptpted = decipher.update（ciphertext，'base64'，'utf8'）; decrypted + = decipher.final（'utf8'）; 返回解密; };

结果是以下异常：

> crypto.js：323 var ret = this._binding.final（）; > ^ TypeError：error：00000000：lib（0）：func（0）：reason（0）>在Decipher.Cipher.final（crypto.js：323：27）> （Object） ）>在Promise。< anonymous> （C：\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\server\api\service\service.controller.js：111：34）> ;在Promise。< anonymous> （C：\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\\\ode_modules\mongoose\\\ode_modules\mpromise\lib\promise.js：177：8）>在Promise.emit（events.js：95：17）>在Promise.emit（C：\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\\\ode_modules\mongoose\\\ode_modules\mpromise\lib\promise.js：84 ：38）>在Promise.fulfill（C：\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\\\ode_modules\mongoose\\\ode_modules\mpromise\lib\promise.js：97 ：20）>在Promise.resolve（C：\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\\\ode_modules\mongoose\lib\promise.js：114：23）>在Promise。< anonymous> （C：\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\\\ode_modules\mongoose\\\ode_modules\mpromise\lib\promise.js：177：8）>在Promise.emit（events.js：95：17）

任何想法？

I created ciphertext with javax.crypto.Cipher org.apachemons.codec.binary.Base64 and using Java like following:

import java.security.NoSuchAlgorithmException; import java.security.NoSuchProviderException; import javax.crypto.Cipher; import javax.crypto.NoSuchPaddingException; import javax.crypto.SecretKey; import javax.crypto.spec.SecretKeySpec; import org.apachemons.codec.binary.Base64; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public final class PwdCipher { private static final Logger LOG = LoggerFactory.getLogger(PwdCipher.class); private static final int BASE64_ARG0 = 32; private static final String SECRET = "tvnw63ufg9gh5392"; private static byte[] linebreak = {}; private static SecretKey key; private static Cipher cipher; private static Base64 coder; static { key = new SecretKeySpec(SECRET.getBytes(), "AES"); try { cipher = Cipher.getInstance("AES/ECB/PKCS5Padding", "SunJCE"); } catch (NoSuchAlgorithmException | NoSuchProviderException | NoSuchPaddingException e) { LOG.debug("Erro ao criar encriptador.", e); } coder = new Base64(BASE64_ARG0, linebreak, true); } private PwdCipher(){ } public static synchronized String encrypt(String plainText) { try { cipher.init(Cipher.ENCRYPT_MODE, key); byte[] cipherText = cipher.doFinal(plainText.getBytes()); return new String(coder.encode(cipherText)); } catch (Exception e) { throw new GdocException("Erro ao encriptar senha.", e); } } public static synchronized String decrypt(String codedText) { try { byte[] encypted = coder.decode(codedText.getBytes()); cipher.init(Cipher.DECRYPT_MODE, key); byte[] decrypted = cipher.doFinal(encypted); return new String(decrypted); } catch (Exception e) { throw new GdocException("Erro ao decriptar senha.", e); } } }

I need to decrypt the text (encrypted with class PwdCipher) using Node.js, but when I use the following code:

exports.decryptLdapPassword = function(password){ var key = 'tvnw63ufg9gh5392'; var ciphertext = password; var crypto = require('crypto'); var decipher = crypto.createDecipher('aes-128-ecb', key); var decrypted = decipher.update(ciphertext, 'base64', 'utf8'); decrypted += decipher.final('utf8'); return decrypted; };

It turns out the following exception:

> crypto.js:323 var ret = this._binding.final(); > ^ TypeError: error:00000000:lib(0):func(0):reason(0) > at Decipher.Cipher.final (crypto.js:323:27) > at Object.exports.decryptLdapPassword (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\server\api\service\service.util.js:14:25) > at Promise.<anonymous> (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\server\api\service\service.controller.js:111:34) > at Promise.<anonymous> (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\node_modules\mongoose\node_modules\mpromise\lib\promise.js:177:8) > at Promise.emit (events.js:95:17) > at Promise.emit (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\node_modules\mongoose\node_modules\mpromise\lib\promise.js:84:38) > at Promise.fulfill (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\node_modules\mongoose\node_modules\mpromise\lib\promise.js:97:20) > at Promise.resolve (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\node_modules\mongoose\lib\promise.js:114:23) > at Promise.<anonymous> (C:\ProjetosTFS\GDOC\fSuporte\GDoc\Versionado\Fontes\woodstock\node_modules\mongoose\node_modules\mpromise\lib\promise.js:177:8) > at Promise.emit (events.js:95:17)

Any idea?
