Key Generation APIs

Most cryptographic operations involve a mathematical formula (algorithm) and secret data (key). The Key Generation APIs allow you to generate random key values for both symmetric and asymmetric (PKA) algorithms.

The Key Generation APIs include:

• Calculate Diffie-Hellman Secret Key (QC3CALDS, Qc3CalculateDHSecretKey) calculates a Diffie-Hellman shared secret key.
• Generate Diffie-Hellman Key Pair (QC3GENDK, Qc3GenDHKeyPair) generates a Diffie-Hellman (D-H) private/public key pair needed for calculating a Diffie-Hellman shared secret key.
• Generate Diffie-Hellman Parameters (QC3GENDP, Qc3GenDHParms) generates the parameters needed for generating a Diffie-Hellman key pair.
• Generate ECC Key Pair (QC3GENECC, Qc3GenECCKeyPair) generates a random ECC key pair given a set of domain parameters to be used with elliptic curve cryptographic algorithms.
• Generate Elliptic Curve Diffie-Hellman Key Pair (QC3GENECDK, Qc3GenECDKeyPair) generates a Diffie-Hellman (D-H) private/public key pair needed for calculating a Diffie-Hellman shared secret key.
• Generate PKA Key Pair (QC3GENPK, Qc3GenPKAKeyPair) generates a random PKA key pair.
• Generate Symmetric Key (QC3GENSK, Qc3GenSymmetricKey) generates a random key value that can be used with a symmetric cipher algorithm
