From: http://blog.csdn.net/lele5000/article/details/6704247 Preface: The implementation of MD5 and base64 functions is not the focus of this article. The focus is on the trouble of Character Set conversion during implementation.   Recently, due to

MD5 and sha1 are one-way encryption Algorithm It is often used for password verification and other scenarios requiring encryption operations. In general, developers can write related functions themselves or use their own functions through Delphi or

Sometimes, in the development process, if you accidentally change the password of the project administrator account and forget, the existence of the password in the database is MD5 encrypted, what happens at this time? The most rookie of me, just

Official definition functions: Hashbytes ( '', { @input | 'input' } )::= MD2 | MD4 | MD5 | SHA | SHA1Parameter explanation:Algorithm: Identifies the hashing algorithm used to perform a hash operation on the input. This is a required parameter with
