KI_RC2WithBSAFE1Params
280 RSA BSAFE Crypto-C Library Reference Manual
KI_RC2WithBSAFE1Params
Purpose:
Deprecated. This type is included only for backward compatibility.
Type of information this allows you to use:
an RC2 key (which is the same as an SX1 key) where the key value and effective key
size are specified. Usually, the effective key size is a parameter to the RC2 encryption
algorithm; however, BSAFE 1.x also encodes the effective key size with the RC2 key.
Format of info supplied to B_SetKeyInfo:
pointer to a B_RC2_BSAFE1_PARAMS_KEY structure:
effectiveKeyBits
must be between 2 and 64, inclusive. The value of
key
is adjusted
when it is copied to the key object by zeroizing unneeded bytes because
effectiveKeyBits
is smaller than 64. For example, if
effectiveKeyBits
is 32 and the
hexadecimal value of
key
is 0102030405060708, then 0102030400000000 is copied to the
key object because only 32 bits (4 bytes) are needed.
Format of info returned by B_GetKeyInfo:
pointer to a B_RC2_BSAFE1_PARAMS_KEY structure (see above). The value of
key
is
adjusted by zeroizing unneeded bytes based on the
effectiveKeyBits
as explained
above.
Can get this info type if key object already has:
KI_RC2WithBSAFE1Params or KI_RC2_BSAFE1.
typedef struct {
unsigned char *key; /* pointer to 8-byte key */
unsigned int effectiveKeyBits; /* effective key size parameter */
} B_RC2_BSAFE1_PARAMS_KEY;
