<!--beginarticle-->
<PRE>I am working towards using the Crypto.PublicKey.RSA encryption and
eventually padding like PKCS#1. I have observed that the leading
'\000' are removed. Is this the desired behavior of bytes_to_long and
long_to_bytes? Or is this not an issue once a good padding scheme is
implemented?
For example: from lib/Crypto/Util/number.py module, using
bytes_to_long and long_to_bytes.
>>><i> teststring
</I>'\x00\x00test\x00\x00'
>>><i> result = bytes_to_long(teststring)
</I>>>><i> result
</I>127979077500928L
>>><i> long_to_bytes(result)
</I>'test\x00\x00'
Thanks,
Anthony Honstain
