    Appends a com.google.protobuf.ByteString a to the sequence of bytes to be hashed.

    Appends a com.google.protobuf.ByteString a to the sequence of bytes to be hashed. Use add for com.google.protobuf.ByteStrings of variable length to prevent hash collisions due to concatenation of variable-length strings.

    Document at the call site in production code why it is not necessary to include a length prefix.
