@ -361,6 +361,11 @@ A: KeyID algorithm changed after that version. If you want, you can manually
rewrite the message sencode envelopes to contain new recipient/signer KeyIDs
and new message identificators, things should work perfectly after that.
Q: I can't read/verify messages from versions 1.7.4 and older!
A: There was a mistake with no security implications in Cubehash
implementation. Same advice as in previous case applies.
Q: Some signatures from version 1.5 and older fail to verify!
A: There was a slight mistake in padding of messages shorter than signature
@ -370,6 +375,13 @@ this minor use-case. If you really need to verify such signatures, edit the
msg_pad function in src/algos_sig.h so that the `load_key()' function is called
on empty vector instead of `out'.
Q: My Cubehash-based FMTSeq key produces invalid signatures after version
1.7.5!
A: Cubehash was corrected to obey standards in 1.7.5. It is possible to
generate a new public key that would work with your private key, but the
general advice is just to generate a new key.
Q: I want to sign/encrypt a large file but it took all my RAM and takes ages!
A: Use \fB--symmetric\fR option. See the `CAVEATS' section for more details.
