Enum CipherSuite 

Source 
pub enum CipherSuite {
    Standard,
    Fips,
}
Expand description

The set of cryptographic algorithms a super::KeyStore is allowed to use, determined by the environment it operates in.

It is set once when the store is constructed (see super::KeyStore::set_cipher_suite) and read through super::KeyStoreContext by operations that must pick a compliant algorithm, such as the KDF for a new account.

Variants§

§

Standard

The default suite, using the modern recommended algorithms (e.g. Argon2id).

§

Fips

The FIPS-compliant suite required in government (FedRAMP) environments, restricted to FIPS-approved algorithms (e.g. PBKDF2).

Implementations§

Source§

impl CipherSuite

Source

pub fn from_gov_mode(gov_mode: bool) -> Self

Returns the CipherSuite for the current environment, given whether the client is in Gov Mode (FedRAMP).

Source

pub fn default_kdf_for_new_account(self) -> Kdf

Returns the KDF a new account should use under this suite.

CipherSuite::Fips uses the FIPS-approved PBKDF2; CipherSuite::Standard uses the modern Argon2id default.

Source

pub fn is_kdf_compliant(self, kdf: &Kdf) -> bool

Returns whether the given KDF is allowed under this suite.

Under CipherSuite::Fips only PBKDF2 is FIPS-approved; under CipherSuite::Standard every supported KDF is allowed.
