Crate argon2_ffi

Foreign Function Interface (FFI) bindings for the rust-argon2 crate.

Return Values

Most functions return an int32_t. On successful completion, the value 0 is returned; otherwise a negative value is returned. The table below shows the meaning of the return values.

Value	Description
0	OK
-1	Output pointer is NULL
-2	Output is too short
-3	Output is too long
-4	Password is too short
-5	Password is too long
-6	Salt is too short
-7	Salt is too long
-8	Associated data is too short
-9	Associated data is too long
-10	Secret is too short
-11	Secret is too long
-12	Time cost is too small
-13	Time cost is too large
-14	Memory cost is too small
-15	Memory cost is too large
-16	Too few lanes
-17	Too many lanes
-18	Password pointer is NULL, but password length is not 0
-19	Salt pointer is NULL, but salt length is not 0
-20	Secret pointer is NULL, but secret length is not 0
-21	Associated data pointer is NULL, bit ad length is not 0
-26	There is no such version of Argon2
-31	Encoding failed
-32	Decoding failed
-35	The password does not match the supplied hash
-36	Hash pointer is NULL, but hash length is not 0
