Both nettle and libgcrypt require that the iv len match the block size of the cipher, so iv-len for 3des must always be 24 Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://entangle-photo.org -o- http://search.cpan.org/~danberr/ :| ^ permalink raw reply [flat|nested] 9+ messages in thread
