6. Public Key cryptography

Public key cryptography, also known as asymmetric cryptography, is an easy way for key management and to provide digital signatures. Libgcrypt provides two completely different interfaces to public key cryptography, this chapter explains the one based on S-expressions.


6.1 Available algorithms		Algorithms supported by the library.
6.2 Used S-expressions		Introduction into the used S-expression.
6.3 Public key modules		How to work with public key modules.
6.4 Cryptographic Functions		Functions for performing the cryptographic actions.
6.5 General public-key related Functions		General functions, not implementing any cryptography.
6.6 Alternative Public Key Interface		Alternative interface to public key functions.
