RSA Security 5 manual KI24Byte, Byte value for symmetric keys such as Desede

KI_24Byte

KI_24Byte

Purpose:

This KI allows you to specify a generic 24-byte key for a symmetric encryption algorithm such as Triple DES. It may also be used as keying material for certain MAC algorithms such as HMAC. See KI_DES24Strong for a Triple DES specific variant of this key info type.

Type of information this allows you to use:

a 24-byte value for symmetric keys such as DES_EDE.

Format of info supplied to B_SetKeyInfo:

pointer to an unsigned char array that holds the 24 bytes.

Format of info returned by B_GetKeyInfo:

pointer to an unsigned char array that holds the 24 bytes.

Can get this info type if key object already has:

KI_24Byte, KI_Item (if the length of the ITEM is 24), KI_DESX.
