Testing if Sha1 is stalled on server

rr1024

Hello All,
Hopefully someone will have some knowledge about these php crypts. I actually have two questions here 🙂

1) ----------------
I know there are some contants that can be checked for MD5 hashing for example we can do this

if ( CRYPT_MD5 )
     $password = md5($password);

But i can't seem to find out what the constent is for sha1 i.e. ??CRYPT_SHA1??

if ( CRYPT_SHA1 )
     $password = sha1($password);

I tried that but it didn't work

2)-----------------------

what is this blowfish thing? I see it being refered to as some type of encyption or hashing but I can't seem to find a php function called blowfish()
They even have a contant for it i.e.

if ( CRYPT_BLOWFISH )
     $password = blowfish($password);

we seem to be missing blowfish() in php?

The constant is PHP_VERSION 😛
Basically, [man]sha1/man is available natively on PHP 4.3.0 onwards, while [man]md5/man has been available since PHP3.

The CRYPT_MD5 constant that you refer to does not refer to this native implementation of MD5 on PHP, but to the availability of MD5 for use with the [man]crypt/man function.

what is this blowfish thing? I see it being refered to as some type of encyption or hashing but I can't seem to find a php function called blowfish()

Blowfish is a 64-bit block cipher. In PHP, one would most likely use it via [man]mcrypt[/man], though there may be some custom implementations available. PHP does not natively support blowfish, so there is no blowfish() function unless it is defined in some custom implementation.

Ok, I think I get it. Thank you very much I was trying to write a function that used what ever was available
Like
if ( CRYPT_MD5 )
$hash = "md5"; #we will use MD5 hashing
elseif (CRYPT_BLOWFISH )
$hash = "blowfish"; #we will use blowfish hashing
elseif (CRYPT_EXT_DES )
$hash = "crypt"; #we will use crypt hashing

Anyway, thanks very much but I guess my idea won't really work, just thought it would be nice to have a function that detected what hashing was installed and have the function automatically choose the level of encryption.
