金蝶K3V12.1用户密码翻译源码，由明文翻译成密文，虽然是在金蝶K3V12.1的版本下做的，但是在金蝶其他的版本上也适用。-Kingdee K3V12.1 user password translation source, the plaintext into ciphertext translation, although in the Kingdee K3V12.1 version to do, but for the other version is also in kingdee.

加密类js进行公钥加密，传输过程没有明文密码，后端进行私钥解密(The encryption class JS carries on the public key encryption, the transmission process has not the clear text password, the back end carries on the private key to decrypt)

DES加解密，明文，密文，私钥皆为16进制，编写 DES 分组密码算法，用 DES 分组密码算法加密的密文 C 解密。
