botan_mp_destroy :: FinalizerPtr BotanMPStruct Source #

Destroy (deallocate) an MPI

botan_mp_init Source #

Arguments

:: Ptr BotanMP	mp
-> IO CInt

Initialize an MPI

botan_mp_to_hex Source #

Arguments

:: BotanMP	mp
-> Ptr CChar	out
-> IO CInt

Convert the MPI to a hex string. Writes botan_mp_num_bytes(mp)*2 + 1 bytes

botan_mp_to_str Source #

Arguments

:: BotanMP	mp
-> Word8	base
-> Ptr CChar	out
-> Ptr CSize	out_len
-> IO CInt

Convert the MPI to a string. Currently base == 10 and base == 16 are supported.

NOTE: base 16 encoding has an `0x` prefix, base 10 does not.

NOTE: Despite the size ptr, this appears to be returning null-terminated CStrings

botan_mp_clear Source #

Arguments

:: BotanMP	mp
-> IO CInt

Set the MPI to zero

botan_mp_set_from_int Source #

Arguments

:: BotanMP	mp
-> CInt	initial_value
-> IO CInt

Set the MPI value from an int

botan_mp_set_from_mp Source #

Arguments

:: BotanMP	dest
-> BotanMP	source
-> IO CInt

Set the MPI value from another MP object

botan_mp_set_from_str Source #

Arguments

:: BotanMP	dest
-> ConstPtr CChar	str
-> IO CInt

Set the MPI value from a string

botan_mp_set_from_radix_str Source #

Arguments

:: BotanMP	dest
-> ConstPtr CChar	str
-> CSize	radix
-> IO CInt

Set the MPI value from a string with arbitrary radix. For arbitrary being 10 or 16.

botan_mp_num_bits Source #

Arguments

:: BotanMP	n
-> Ptr CSize	bits
-> IO CInt

Return the number of significant bits in the MPI

botan_mp_num_bytes Source #

Arguments

:: BotanMP	n
-> Ptr CSize	bytes
-> IO CInt

Return the number of significant bytes in the MPI

botan_mp_to_bin Source #

Arguments

:: BotanMP	mp
-> Ptr Word8	vec[]
-> IO CInt

Convert the MPI to a big-endian binary string. Writes botan_mp_num_bytes to vec

botan_mp_from_bin Source #

Arguments

:: BotanMP	mp
-> ConstPtr Word8	vec[]
-> CSize	vec_len
-> IO CInt

Set an MP to the big-endian binary value

botan_mp_to_uint32 Source #

Arguments

:: BotanMP	mp
-> Ptr Word32	val
-> IO CInt

Convert the MPI to a uint32_t, if possible. Fails if MPI is negative or too large.

botan_mp_is_positive Source #

Arguments

:: BotanMP	mp
