      crypto/sha1, crypto/sha256, crypto/sha512: use copy for partial block · 29fe067b
      Joel Sing authored
      Use copy rather than a hand rolled loop when moving a partial input
      block to the scratch area. This results in a reasonable performance
      gain when partial blocks are written.
