#25177 [NEW]: Sha1 doesnt work correct with data greater then 2kB
From: a dot lunkeit at signcubes dot com
Operating system: Linux
PHP version: 4.3.2
PHP Bug Type: *Encryption and hash functions
Bug description: Sha1 doesnt work correct with data greater then 2kB
Description:
------------
I noticed, that the sha1 function computes wrong hash values for data with
a volume greater than 2kB.
My reference values are various free implementations in C++, which come to
the same hash value, but the PHP implementation differs.
With data smaller than 2kB the problem does not exist.
Reproduce code:
---------------
This can be any code using the sha1 function. My code example doesn't
really matter.
