aescipher-java's Introduction

AESCipher-Java

AES Encryption For Java

Using this code for Android and Java back-end and AESCipher-iOS for iOS lets you encrypt and decrypt with AES accurately.

Encryption:

// For String
public static String aesEncryptString(String content, String key)
// For Bytes
public static byte[] aesEncryptBytes(byte[] contentBytes, byte[] keyBytes)

Decryption:

// For String
public static String aesDecryptString(String content, String key)
// For Bytes
public static byte[] aesDecryptBytes(byte[] contentBytes, byte[] keyBytes)

Additionally you can modify the IV_STRING with another 16 bytes string in line 23 of AESCipher.java , but you should make sure to keep it the same with kInitVector in line 14 of AESCipher-iOS.


用 Java 实现的 AES 加密。

AESCipher-iOS 一并使用能达到 在iOS、Android、Java后台产生相同密文、正确解密成明文的目的。

加密方法:

// For String
public static String aesEncryptString(String content, String key)
// For Bytes
public static byte[] aesEncryptBytes(byte[] contentBytes, byte[] keyBytes)

解密方法:

// For String
public static String aesDecryptString(String content, String key)
// For Bytes
public static byte[] aesDecryptBytes(byte[] contentBytes, byte[] keyBytes)

另外你也可以将 AESCipher.java 第 23 行中的 IV_STRING 修改为其他 16 字节的字符串,但请确保其与 AESCipher-iOS 第 14 行处的 kInitVector 保持一致。

aescipher-java's Issues

AESCipher-JavaScript-Or-QML

    var iv = "16-Bytes--String";
    function encryptAES(content, key) {
        var AES = CryptoJS.AES;
        var ivStr  = CryptoJS.enc.Utf8.parse(iv);
        var keyStr = CryptoJS.enc.Utf8.parse(key);

        var text = AES.encrypt(content, keyStr, {
                                        iv: ivStr,
                                        mode: CryptoJS.mode.CBC,
                                        padding: CryptoJS.pad.Pkcs7
                                    });
        return text.toString();
    }

    function decryptAES(ciphertext, key) {
        var AES = CryptoJS.AES;
        var ivStr  = CryptoJS.enc.Utf8.parse(iv);
        var keyStr = CryptoJS.enc.Utf8.parse(key);

        var bytes = AES.decrypt(ciphertext, keyStr, {
                                        iv: ivStr,
                                        mode: CryptoJS.mode.CBC,
                                        padding: CryptoJS.pad.Pkcs7
                                    });
        var plaintext = bytes.toString(CryptoJS.enc.Utf8);
        return plaintext.toString();
    }

Use brix/crypto-js lib.

作者您好,解密的时候出现乱码,但是我设置的时候,使用的是aesDecryptString 这个方法

我查看了源码,您源码中默认的编码格式是UTF-8.

而且大部分情况加解密是没问题的.我们只有一个用户出现这种情况.出现的乱码是这样的.

解密后的乱码是这样的.

不知道作者是否有遇到这个情况.
