Re-2: des encryption with rev for .htaccess password

[runrev260805 at m-r-d.de]

Hi Mark,

i have to admit, that i am not very familiar with php and its encryption. 

This is what i found at php.net about crypt. PHP uses a random key if none is provided.

crypt() will return an encrypted string using the standard Unix DES-based encryption algorithm or alternative algorithms that may be available on the system. 

Some operating systems support more than one type of encryption. In fact, sometimes the standard DES-based encryption is replaced by an MD5-based encryption algorithm. The encryption type is triggered by the salt argument. At install time, PHP determines the capabilities of the crypt function and will accept salts for other encryption types. If no salt is provided, PHP will auto-generate a standard two character salt by default, unless the default encryption type on the system is MD5, in which case a random MD5-compatible salt is generated. PHP sets a constant named CRYPT_SALT_LENGTH which tells you whether a regular two character salt applies to your system or the longer twelve character salt is applicable. 

The standard DES-based encryption crypt() returns the salt as the first two characters of the output. It also only uses the first eight characters of str , so longer strings that start with the same eight characters will generate the same result (when the same salt is used).
