RSA Security 5 manual KIECPublicBER

KI_ECPublicBER

KI_ECPublicBER

Purpose:

This KI allows you to specify a public key used by the Elliptic Curve algorithm. The information consists of the public component and the underlying elliptic curve parameters.

Type of information this allows you to use:

the encoding of an ANSI X9.62-compliant key object identifier that defines an elliptic curve public key. The parameters of the key are specified as the public component (publicKey), and the underlying elliptic curve parameters.

Format of info supplied to B_SetKeyInfo:

pointer to an ITEM structure that contains the ANSI X9.62 compliant BER encoding of a public key and its elliptic curve parameters. In compliance with X9.62, you can specify the CHOICE of either a full EC CURVE definition or a NAMED CURVE definition. Both ANSI X9.62 uncompressed and hybrid base points are decoded.

Format of info returned by B_GetKeyInfo:

pointer to an ITEM structure that contains the ANSI X9.62 compliant BER encoding of an elliptic curve’s parameters. Note that the re-encoded BER will preserve the original X9.62 NAMED CURVE representation of the elliptic curve parameters.

Can get this info type if key object already has:

KI_ECPublic or KI_ECPublicBER.
