MD5_FILE(3) 1 MD5_FILE(3)md5_file - Calculates the md5 hash of a given fileSYNOPSIS
string md5_file (string $filename, [bool $raw_output = false])
DESCRIPTION
Calculates the MD5 hash of the file specified by the $filename parameter using the RSA Data Security, Inc. MD5 Message-Digest Algorithm,
and returns that hash. The hash is a 32-character hexadecimal number.
PARAMETERS
o $filename
- The filename
o $raw_output
- When TRUE, returns the digest in raw binary format with a length of 16.
RETURN VALUES
Returns a string on success, FALSE otherwise.

SHA1(3) 1 SHA1(3)sha1 - Calculate the sha1 hash of a stringSYNOPSIS
string sha1 (string $str, [bool $raw_output = false])
DESCRIPTION
Calculates the sha1 hash of $str using the US Secure Hash Algorithm 1.
PARAMETERS
o $str
- The input string.
o $raw_output
- If the optional $raw_output is set to TRUE, then the sha1 digest is instead returned in raw binary format with a length of 20,
otherwise the returned value is a 40-character hexadecimal number.
RETURN VALUES
Returns the sha1 hash as a string.
EXAMPLES
Example #1
A sha1(3) example
<?php
$str = 'apple';
if (sha1($str) === 'd0be2dc421be4fcd0172e5afceea3970e2f3d940') {
echo "Would you like a green or red apple?";
}
?>
NOTES
Note
Secure password hashing
It is not recommended to use this function to secure passwords, due to the fast nature of this hashing algorithm. See here for
details.

hi
i want to generate MD5 hash of string in unix (hp) i have the algorithm which takes file as argument and returns hash of file but when i tried to generate hash of "a" result was "60b725f10c9c85c70d97880dfe8191b3" hash but actually it should have been "0cc175b9c0f1b6a831c399e269772661" now i...

I am trying to use John the Ripper but it doesn't take regular MD5 hashes, only shadow MD5 hashes. For example this hash: 900150983cd24fb0d6963f7d28e17f72 (which, decrypted, is 'abc') within a text file, John the Ripper does not detect because it is not in shadow format. How can I convert this MD5... (2 Replies)

Hi Guys,
I have a backup program that creates incremental backups and generates a MD5 hash at the same time.
Each server backup has its own sub folder.
Each backup file has a corresponding .md5 file containing a hash and a file name like this.
