Random number generation algorithms identifiers

Variants

Rng

The random-number generator algorithm.

Standard: FIPS 186-2, FIPS 140-2, NIST SP 800-90

Beginning with Windows Vista with SP1 and Windows Server 2008, the random number generator is based on the AES counter mode specified in the NIST SP 800-90 standard.

Windows Vista: The random number generator is based on the hash-based random number generator specified in the FIPS 186-2 standard.

Windows 8: Beginning with Windows 8, the RNG algorithm supports FIPS 186-3. Keys less than or equal to 1024 bits adhere to FIPS 186-2 and keys greater than 1024 to FIPS 186-3.

DualECRng

The dual elliptic curve random-number generator algorithm.

Standard: SP800-90.

Windows 8: Beginning with Windows 8, the EC RNG algorithm supports FIPS 186-3. Keys less than or equal to 1024 bits adhere to FIPS 186-2 and keys greater than 1024 to FIPS 186-3.

Windows 10: Beginning with Windows 10, the dual elliptic curve random number generator algorithm has been removed. Existing uses of this algorithm will continue to work; however, the random number generator is based on the AES counter mode specified in the NIST SP 800-90 standard. New code should use Rng, and it is recommended that existing code be changed to use Rng.

Fips186DsaRng

The random-number generator algorithm suitable for DSA (Digital Signature RandomAlgorithmId).

Standard: FIPS 186-2.

Windows 8: Support for FIPS 186-3 begins.

Trait Implementations

impl Clone for RandomAlgorithmId

fn clone(&self) -> RandomAlgorithmId

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Display for RandomAlgorithmId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<RandomAlgorithmId> for &'static str

fn from(val: RandomAlgorithmId) -> Self

Converts to this type from the input type.

impl PartialEq for RandomAlgorithmId

fn eq(&self, other: &RandomAlgorithmId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for RandomAlgorithmId

fn partial_cmp(&self, other: &RandomAlgorithmId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> TryFrom<&'a str> for RandomAlgorithmId

type Error = &'a str

The type returned in the event of a conversion error.

fn try_from(value: &'a str) -> Result<RandomAlgorithmId, Self::Error>

Performs the conversion.
