Class Crypto

Namespace

CSharpToJavaScript.APIs.JS

Assembly

CSharpToJavaScript.dll

The Crypto interface represents basic cryptography features available in the current context.
It allows access to a cryptographically strong random number generator and to cryptographic primitives.

[Value("Crypto")]
public class Crypto

Inheritance

object

Crypto

Inherited Members

object.GetType()

object.MemberwiseClone()

Remarks

The Crypto is available in windows using the Window.Crypto property and in workers using the WorkerGlobalScope.Crypto property.

Properties

Subtle

The Crypto.subtle read-only property returns a
SubtleCrypto which can then be used to perform low-level
cryptographic operations.

[Value("subtle")]
public SubtleCrypto Subtle { get; }

Property Value

SubtleCrypto

A SubtleCrypto object you can use to interact with the Web Crypto API's
low-level cryptography features.

Remarks

-Crypto.
-SubtleCrypto.
-Compatibility test page.
-Shim for IE11 and Safari.

Methods

GetRandomValues(Union223)

The Crypto.getRandomValues() method lets you get cryptographically strong random values.
The array given as the parameter is filled with random numbers (random in its cryptographic meaning).

[Value("getRandomValues")]
public Union223 GetRandomValues(Union223 array)

Parameters

array Union223

Returns

Union223

The same array passed as typedArray but with its contents replaced with the newly generated random numbers.
Note that typedArray is modified in-place, and no copy is made.

Remarks

To guarantee enough performance, implementations are not using a truly random number generator, but they are using a pseudo-random number generator seeded with a value with enough entropy.
The pseudo-random number generator algorithm (PRNG) may vary across user agent, but is suitable for cryptographic purposes.

getRandomValues() is the only member of the Crypto interface which can be used from an insecure context.

-Web Crypto API
-MathRandom, a non-cryptographic source of random numbers.

RandomUUID()

The randomUUID() method of the Crypto interface is used to generate a v4 {{Glossary("UUID")}} using a cryptographically secure random number generator.

[Value("randomUUID")]
public string RandomUUID()

Returns

string

A string containing a randomly generated, 36 character long v4 UUID.

Remarks

-Web Crypto API
-GetRandomValues(Union223), a source for arbitrary amounts of secure random bytes.
