WebDec 23, 2015 · In any case the minimal recommended length for K is L bytes (as the hash output length). So preferably the entropy of the 256 bit key should be condensed into 32 bytes. What you are talking about is probably the hexadecimal representation of those 32 bytes. If the key is too large it may affect performance and efficiency of the HMAC function.

"WebJun 10, 2024 · For the key length, you should use at least 2048 (NSA recommends 3072 or larger ref ). Note that RSA can only encrypt data up to the key length (including padding). So, with a key of 2048 bits, you cannot encrypt a blob of 4096 bits. You'll need to split it into 2 blobs and encrypt them separately. C# " - Crypto outputlength

WebCrypto.Util.number.long_to_bytes(n, blocksize=0) Convert a positive integer to a byte string using big endian encoding. If blocksize is absent or zero, the byte string will be of minimal length. Otherwise, the length of the byte string is guaranteed to be a multiple of blocksize. If necessary, zeroes ( \x00) are added at the left.
