I'm not exactly sure what I will need, yet, but certainly if it was easy for ABCL to provide a fast way to compute the SHA1/SHA256/SHA512 digest of disk files, that would be helpful. […]

Attached please find code for ABCL which directly manipulates the underlying JVM APIs for fast I/O ("NIO") and uses the built-in MessageDigest computation. Is this sufficient for your needs? ABCL needs to look at how to make such things happen natively in Lisp a lot faster, but that won't be happening in the near future. -- "A screaming comes across the sky.
