Assymetric Encryption question??

[Shane Story]

Hello all,

I am a bit confused by the Assym. encrpyption.. Many say that it can only
encrypt like 100bytes or so. If so what good is that? Or does this mean
one should loop through a file encrypting 100byte chunks until it is all
encrypted?

Sort of wanted to create a PGP like program/library for various uses.

Also, I have seen folks use public key encryption for their software--you
purchase the Key and it comes as I suppose a public key string that is read
by the software which must have the private key.

Any suggestions on implementing such a strategy or on how to use ASSYM
encryption on large files?

Thanks,

Shane

A terific lot of stuff about your question

In the resourcekit is an example for encrypting files.

And if you have problems installing it
