Module params 

Limits, Algorithm, Version and Params.

Every constant here is transcribed from phc-winner-argon2/include/argon2.h and phc-winner-argon2/src/core.h. validate_inputs reproduces validate_inputs() from src/core.c in the same order, because the order decides which error code surfaces first.

Structs

Memory

A memory cost, carried in kibibytes.

Params

Validated Argon2 cost parameters.

ParamsBuilder

Builder for Params.

TagLen

A tag length, carried in bytes.

Algorithm

The Argon2 primitive type (argon2_type).

Version

The Argon2 version (argon2_version).
