odp_bool_t odp_crypto_auth_capability_t::bit_mode

Auth algorithm supports bit mode.

This auth algorithm can work on a range of bits in addition to a range of bytes. When this capability is not present, only byte ranges are supported. The unit of auth range is selected at session creation through the auth_range_in_bits session parameter.

Note: In bit mode the auth range must start on a byte boundary. Using an offset which is not divisible by 8 will result in undefined behaviour.

Note2: If the range length in bit mode is not a multiple of 8, the remaining bits of the data in the last byte of the input/output will be the most significant bits, i.e. the most significant bit is considered to be the first bit of a byte for the purpose of input and output data range. The output bits that fall out of the output range are undefined.

Examples

ipsec_crypto/odp_ipsec.c, and odp_crypto.c.
