    Variables

    PARAMS_OWASP ¶
    Source

    @(rodata)
PARAMS_OWASP: Parameters = …
     

    PARAMS_OWASP is one of the recommended parameter set from the OWASP Password Storage Cheat Sheet (as of 2026/02). The cheat sheet contains additional variations to this parameter set with various trade-offs between memory_size and passes that are intended to provide equivalent security.

    See: https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html

    PARAMS_OWASP_SMALL ¶
    Source

    @(rodata)
PARAMS_OWASP_SMALL: Parameters = …
     

    PARAMS_OWASP_SMALL is equivalent in strength to PARAMS_OWASP, but trades off less memory use for more CPU usage.

    PARAMS_RFC9106 ¶
    Source

    @(rodata)
PARAMS_RFC9106: Parameters = …
     

    PARAMS_RFC9106 is the first recommended "uniformly safe" parameter set per RFC 9106.

    PARAMS_RFC9106_SMALL ¶
    Source

    @(rodata)
PARAMS_RFC9106_SMALL: Parameters = …
     

    PARAMS_RFC9106_SMALL is the second recommended "uniformly safe" parameter set per RFC 9106 tailored for memory constrained environments.

    Procedures

    derive ¶
    Source

    derive :: proc(
	parameters: ^Parameters, 
	password:   []u8, 
	salt:       []u8, 
	dst:        []u8, 
	secret:     []u8 = nil, 
	ad:         []u8 = nil, 
	sanitize:   bool = true, 
	allocator := context.allocator, 
) -> runtime.Allocator_Error {…}
     

    derive invokes Argon2id with the specified parameter set and inputs, and outputs the derived key to dst.
