Subtlecrypto examples
Web14 May 2014 · I did find one way of getting this to work with a built in library to C# called Rfc2898DeriveBytes. Using this, I get a valid output using: Rfc2898DeriveBytes k3 = new Rfc2898DeriveBytes (pwd1, salt1, 4096); byte [] answers = k3.GetBytes (32); Now, the one limitation I have using Rfc2898DeriveBytes is the "salt" must be 8 octets long. WebSubtleCrypto interface encrypts data. It takes as its arguments a key to encrypt with, some algorithm-specific parameters, and the data to encrypt (also known as "plaintext"). It returns a Promise which will be fulfilled with the encrypted data (also known as "ciphertext"). Syntax const result = crypto .subtle.encrypt (algorithm, key, data) ;
