a simple and clear explanation about PKCS

[kineri]

Hi all. I am back again!
I am going to do a project which uses PKCS. What is PKCS?
Also, could anyone tell me the difference between PKCS#11 and PKCS#15 in a simple and clear explanation?

FYI:
PKCS is the abbreviation of "Public-Key Cryptography Standards"

PKCS #11: Cryptographic Token Interface Standard
PKCS #15: Cryptographic Token Information Format Standard

BTW: I don't remember a way to access PKCS#15 tokens on a JavaCard from within an oncard JavaCard program. If you want to use keys in your oncard program, you have to transfer it onto the card or generate it oncard and export the public key by your own oncard/offcard code.
