Detailed Description

BYO_CRYPTO: Base class for custom HMAC implementations.

If using BYO_CRYPTO, you must define concrete implementations for the required HMAC algorithms and set their creation callbacks via functions like ApiHandle.SetBYOCryptoNewSHA256HMACCallback().

Member Function Documentation

virtual bool Aws::Crt::Crypto::ByoHMAC::DigestInternal ( ByteBuf output,
size_t  truncateTo = 0 
)
protectedpure virtualnoexcept

Complete the HMAC computation and write the final digest to output. This cannote be called more than once. If truncate_to is something other than 0, the output must be truncated to that number of bytes. Raise an AWS error and return false to indicate failure.

virtual bool Aws::Crt::Crypto::ByoHMAC::UpdateInternal ( const ByteCursor toHash)
protectedpure virtualnoexcept

Updates the running HMAC with to_hash. This can be called multiple times. Raise an AWS error and return false to indicate failure.
