C #: use MD5 to encrypt and decrypt user passwords,

C #: use MD5 to encrypt and decrypt user passwords, C # usually involves encryption and decryption algorithms for user passwords. using MD5 encryption is the most common implementation method. This article summarizes common algorithms and shares

MD5 Encryption algorithm

MD5 is a secure hashing algorithm, input two different plaintext will not get the same output value, according to the output value, can not get the original plaintext, that is, its process is irreversible; So to decrypt MD5 there is no ready-made

Use des and MD5 to encrypt. decrypt. String. File

// Encrypted string. Note that the strencrkey length is 8 bits. (to increase or decrease the key length, adjust the IV length)Public String desencrypt (string strtext, string strencrkey)  // Decrypt the string. Note that the strencrkey length is 8

Deep understanding of Android MD5 Data encryption _android

MD5 encryption MD5 by MD2, MD3, MD4 evolved, although the MD5 encryption algorithm now some people have to untie it, but its encryption mechanism is still very strong, I think the big logarithm will not be solved. MD5 encryption algorithm is

The MD5 of the Java encryption and decryption technology series

OrderIn the previous article, we introduced the most basic coding method--base64, and also briefly mentioned the principle of coding. This article continues to decrypt the series, of course, is also the introduction of a comparative basis of the
