Class AesCtrParams

Namespace

CSharpToJavaScript.APIs.JS

Assembly

CSharpToJavaScript.dll

The AesCtrParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into Encrypt(Union187, CryptoKey, Union224), Decrypt(Union187, CryptoKey, Union224), WrapKey(KeyFormat, CryptoKey, CryptoKey, Union187), or UnwrapKey(KeyFormat, Union224, CryptoKey, Union187, Union187, bool, List<KeyUsage>), when using the AES-CTR algorithm.

Remarks

AES is a block cipher, meaning that it splits the message into blocks and encrypts it a block at a time. In CTR mode, every time a block of the message is encrypted, an extra block of data is mixed in. This extra block is called the &quot;counter block&quot;.

A given counter block value must never be used more than once with the same key:

Typically this is achieved by splitting the initial counter block value into two concatenated parts:

Essentially: the nonce should ensure that counter blocks are not reused from one message to the next, while the counter should ensure that counter blocks are not reused within a single message.

NOTE

See Appendix B of the NIST SP800-38A standard for more information.

-CTR mode is defined in section 6.5 of the NIST SP800-38A standard.
