Modules

aeskey	Symmetric encryption / decryption wrapper.
algorithms	These are algorithms that are used by various policies or external to this file
certificate_store	The certificate store holds and retrieves private keys and certificates from disk. It is responsible for checking certificates supplied by the remote end to see if they are valid and trusted or not.
hash	Hashing functions used for producing and verifying digital signatures
pkey	Asymmetric encryption / decryption, signing / verification wrapper.
security_policy	Security policy is the symmetric, asymmetric encryption / decryption + signing / verification algorithms to use and enforce for the current session.
thumbprint	Functionality for holding a message digest.
x509

Constants

SHA1_SIZE
SHA256_SIZE

Functions

concat_data_and_nonce
create_signature_data	Creates a SignatureData object by signing the supplied certificate and nonce with a pkey
verify_signature_data	Verifies that the supplied signature data was produced by the signing cert. The contained cert and nonce are supplied so the signature can be verified against the expected data.
