Encrypt-java

• Features: encrypt, decrypt, hash code, md5
• Platform: Android, PC
• Encrypt algorithm: DES, AES
• Hash algorithm: MD2, MD5, SHA1, SHA256...

Usage

Encrypt

    String content = "Test content";
    String password = "password";
    String encrypted = EncryptUtil.encrypt(content, password);

Decrypt

    String encrypted = "c73ba17d16f44b8c9e2232200aad11b81070740774d468892c79aca4ac96e5d3";
    String password = "password";
    String decrypted = EncryptUtil.decrypt(encrypted, password);

hash value (md5, sha1, sha256...)

    EncryptUtil.md5("Test content");
    // or
    EncryptUtil.digest("Test content", EncryptUtil.ALGORITHM.MD5);
    EncryptUtil.digest("Test content", EncryptUtil.ALGORITHM.SHA256);

Test sample

    String content = "Test content, 测试测试";
    String password = "password!@#";
    System.out.println("content:" + content + "\n");

    String encrypted = EncryptUtil.encrypt(content, password);
    System.out.println("AES encrypt:" + encrypted);
    System.out.println("AES decrypt:" + EncryptUtil.decrypt(encrypted, password) + "\n");

    encrypted = EncryptUtil.encrypt(content, password, EncryptUtil.ALGORITHM.DES);
    System.out.println("DES encrypt:" + encrypted);
    System.out.println("DES decrypt:" + EncryptUtil.decrypt(encrypted, password, EncryptUtil.ALGORITHM.DES) + "\n");

    System.out.println("md5 hash:" + EncryptUtil.md5(content));
    System.out.println("sha256 hash:" + EncryptUtil.digest(content, EncryptUtil.ALGORITHM.SHA256));
