You should use the complete result obtained by crypt () as the salt value for password verification to avoid problems caused by different hash algorithms. (As described above, the password hash based on the standard DES algorithm uses a 2-character

This article mainly for you in detail the PHP use Crypt () function to encrypt, with a certain reference value, interested in small partners can refer to
One, the code
encryption $str after the variable is: '. $crypttostr; Output encrypted
For everyone to introduce in detail PHP using crypt () function for encryption, has a certain reference value, interested in small partners can refer to
One, the code
encryption $str after the variable is: '. $crypttostr; Output encrypted
Appendix C. Encryption
As a security-related book, encryption is usually a topic to be mentioned. The reason why I ignore encryption in the main part of this book is that it is used in a narrow sense, and developers should focus on security issues.

The MD5 (message-digest algorithm 5) module is used to compute the information ciphertext (Information Digest) and to obtain a 128-bit ciphertext. The SHA module is similar to MD5, but generates a 160-bit signature. The use method is the same.
The
My answer, but the complexity is not very satisfied, is an exponential level of complexity. But the test data is weak, or AC. Found on the Internet, are brute force solution, do not know whether there is a better solution.Two errors were made in the
Although encryption is effective, encryption does not magically improve the security of an application. a PHP developer should be familiar with the following encryption methods:
L symmetric encryption
L asymmetric encryption (public key)
L Hash
Introduction of several ways to implement encryption in PHP
This article mainly introduces the PHP implementation of several methods of encryption, very comprehensive and practical, are often needed in the project, the need for friends can refer to

Parameters
STR--the original string.
