Apache htpasswd decrypt

Active Oldest Votes. Mils: It hashes the password you submit and compares the hash values. Apache takes the password provided, hashes it and compares the username provided and the generated hash to the username if it exists entry in the. If they match the user is allowed. Yes you can. You need to know which hash algorithm is used.

Hey there, I tried to use the both algorithm; Crypt and MD5 But I have a problem when I compare the two passwords, with my code I obtain all time the same password crypted.

I noticed that for the same password if you repeat the process Apache2 generate another encrypted password. Apache uses a salt in the MD5 algorithm. Show 4 more comments.

Since the MD5 function is commonly available, other software can populate a database with encrypted passwords that are usable by Apache digest authentication.

It can encrypt and display password information for use in other types of data stores, though. To use a DBM database see dbmmanage or htdbm. Files managed by htpasswd may contain a mixture of different encoding types of passwords; some user records may have bcrypt or MD5-encrypted passwords while others in the same file may have passwords encrypted with crypt.

This manual page only lists the command line arguments. Adds or modifies the password for user jsmith. The user is prompted for the password. The password will be encrypted using the modified Apache MD5 algorithm. If the file does not exist, htpasswd will do nothing except return an error.

Creates a new file and stores a record in it for user jane. If the file exists and cannot be read, or cannot be written, it is not altered and htpasswd will display a message and return an error status. Encrypts the password from the command line Pwd4Steve using the crypt algorithm, and stores it in the specified file.

Web password files such as those managed by htpasswd should not be within the Web server's URI space -- that is, they should not be fetchable with a browser. The use of the -b option is discouraged, since when it is used the unencrypted password appears on the command line. When using the crypt algorithm, note that only the first 8 characters of the password are used to form the password.

If the supplied password is longer, the extra characters will be silently discarded. The SHA encryption format does not use salting: for a given password, there is only one encrypted representation.

The crypt and MD5 formats permute the representation by prepending a random salt string, to make dictionary attacks against the passwords more difficult. On the Windows platform, passwords encrypted with htpasswd are limited to no more than characters in length. Longer passwords will be truncated to characters.
