I was curious about setting SAH-3 as the preferred hashing algorithm for GPG but that looks like it is not yet supported and the documentation states this:
SHA-3: SHA-3 is a completely new hash algorithm that makes a clean break with the previous SHAs. It is believed to be safe, with no warnings about its usage. It hasn’t yet been officially introduced into the OpenPGP standard, and for that reason GnuPG doesn’t support it. However, SHA-3 will probably be incorporated into the spec, and GnuPG will support it as soon as it does.
What does this means:
...and GnuPG will support it as soon as it does? Are there any development plans for supporting SHA3 or BLAKE?
