[dev] Horde_Cipher et al;

[Davey]

Hi,

I'm currently looking into developing a XML Encryption package for PEAR, 
I have already decided to support the following:

* HMAC
* mcrypt
* mhash
* PGP/GPG (by way of this class [1] that Chuck has kindly offered to 
PEARize)

However, apart from the HMAC solution which only offers message 
integrity checking, no encryption, all of these require
some sort of other dependendy to be installed and I would like to offer 
some userland implementations to get around this.

To that end, I have been pointed to [2] and was wondering a few things,

1) Are they fast enough to actually use? Obviously I don't expect them 
to be as fast as the mcrypt library
2) Is anyone who actually knows the code, willing to PEARize them? I 
think they would need to be completely seperate entitys
so no more central Horde_Cipher class which is extended by the cipher 
driver... however, personally I like this way, a unified API
where possible is always good!
3) Does anyone object to me PEARizeing and submitting to PEAR if no-one 
else will take up the challenge? I don't know the code
and have no knowledge of the ciphers themselves so I would be reluctant 
to do this on my own...

Well, thanks for reading, hope to hear something soon :)
