Wrapper around KeyDerivation to enforce correct Inputs

Variants

Hkdf

HKDF algorithm.

Fields of Hkdf

hash_alg: Hash

A hash algorithm to use

salt: Option<Input<'a>>

Salt, used in the “extract” step. It is optional; if omitted, the derivation uses an empty salt. Typically a direct input, can also be a key of type RawData.

secret: InputSecret<'a>

Secret, used in the “extract” step. This is typically a key of type Derive , or the shared secret resulting from a key agreement, using Input::KeyAgreement. Must be a key or key agreement input if used with psa_key_derivation_output_key.

info: Input<'a>

Info, used in the “expand” step. Typically a direct input, can also be a key of type RawData.

Tls12Prf

TLS-1.2 PRF algorithm.

Fields of Tls12Prf

hash_alg: Hash

A hash algorithm to use.

seed: Input<'a>

Seed, typically a direct input, can also be a key of type RawData.

secret: InputSecret<'a>

Secret, used in the “extract” step. This is typically a key of type Derive , or the shared secret resulting from a key agreement, using Input::KeyAgreement. Must be a key or key agreement input if used with psa_key_derivation_output_key.

label: Input<'a>

Label. Typically a direct input, can also be a key of type RawData.

Tls12PskToMs

TLS-1.2 PSK-to-MasterSecret algorithm.

Fields of Tls12PskToMs

hash_alg: Hash

A hash algorithm to use.

seed: Input<'a>

Seed, typically a direct input, can also be a key of type RawData.

secret: InputSecret<'a>

Secret, used in the “extract” step. This is typically a key of type Derive , or the shared secret resulting from a key agreement, using Input::KeyAgreement. Must be a key or key agreement input if used with psa_key_derivation_output_key. Must not be larger than PSA_TLS12_PSK_TO_MS_PSK_MAX_SIZE.

label: Input<'a>

Label. Typically a direct input, can also be a key of type RawData.
