generateKeypair

public abstract org.bouncycastle.asn1.pkcs.PrivateKeyInfo generateKeypair(String keyspec)
                                                                   throws XiSecurityException

Generate keypair for the given keyspec as defined in RFC 5958.

Parameters:

keyspec - Key specification. It has the following format:

• RSA: 'RSA/'<bit-length> or 'RSA/'<bit-length>

• XDH: 'X25519' or 'X448'

Returns:

the generated keypair.

Throws:

XiSecurityException - if could not generate keypair.
