md5 encode

PHP encryption function-md5 () function encryption what is MD5 () function? MD5 () function is the MD5 hash value of the calculator string, using MD5 algorithm, the full name of MD5 is Message-DigestAlgorithm5, it is used to calculate data

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 simple Java encryption algorithm is:BASE64 strictly speaking, it belongs to the encoding format, not the encryption algorithmMD5 (Message Digest algorithm 5, Information Digest algorithm)SHA (Secure Hash algorithm, security hashing

Currently, the MD5 password database has a huge amount of data, and most common passwords can reverse query the plaintext of the password through the MD5 Digest. To prevent internal personnel (persons who can access database or database backup files)

Algorithm series 9 MD5, algorithm 9 md5   MD5 is the Message-Digest Algorithm 5 (Information-Digest Algorithm 5), which is used to ensure the integrity and consistency of information transmission. It is one of the widely used Hash Algorithms in

MD5 's full name is Message-digest algorithm 5, developed by the MIT Computer Science Lab and RSA Data Security Inc in the early 90, with the development of MD2, MD3 and MD4.MD5 transforms any length of "byte string" into a large integer of 128bit,
