convert text to md5

MD5 encryption and md5 decryptionZookeeper First, let's briefly introduce MD5. The full name of MD5 is message-digest algorithm 5 (Information-digest algorithm, which was developed by mit laboratory for computer science and rsa data security inc

Use the MD5 conversion algorithm to prevent brute force cracking. MD5 is the most common cryptographic algorithm in Web applications. Because MD5 is irreversible, the ciphertext obtained after MD5 calculation cannot be obtained through reverse

Comments: For a long time, MD5 encryption and verification are very secure. Many forums and software Save the password of the user name after MD5 encryption. Compared with the previous plaintext storage, the stored information after MD5 encryption

MD5 is the most common cryptographic algorithm in Web applications. Because MD5 is irreversible, the ciphertext obtained after MD5 calculation cannot be obtained through reverse algorithms. Looking back at the original intention of using MD5 to

I. Brief description MD5: All called message digest algorithm 5 (Information digest algorithm), can be encrypted, but not decrypted, belong to one-way encryption, usually used for file verification BASE64: The 8-bit byte of any sequence is

the MD5 algorithm has the following characteristics:1, compressibility: Any length of data, calculated the length of the MD5 value is fixed. 2, easy to calculate: It is easy to calculate the MD5 value from the original data. 3, anti-modification:

MD5 Introduction MD5 's full name, Message-digest algorithm 5, was developed by the MIT Computer Science Lab and RSA Data Security Inc in the early 90, through MD2, MD3 and MD4. Message-digest refers to the hash transformation of a byte string
