Detailed Description

BYO_CRYPTO: Base class for custom hash implementations.

If using BYO_CRYPTO, you must define concrete implementations for the required hash algorithms and set their creation callbacks via functions like ApiHandle.SetBYOCryptoNewMD5Callback().

Member Function Documentation

DigestInternal()

virtual bool Aws::Crt::Crypto::ByoHash::DigestInternal ( ByteBuf &  output, size_t  truncateTo = 0  )

protectedpure virtualnoexcept

Complete the hash computation and write the final digest to output. This cannot 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.

UpdateInternal()

virtual bool Aws::Crt::Crypto::ByoHash::UpdateInternal ( const ByteCursor &  toHash )

protectedpure virtualnoexcept

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