I'm trying to add support for the sharedpubkey encryption scheme, and while decrypting the files is straight-forward, I cannot get the \"lookup_key\" function to work with this scheme. I tried the following:
# Pull out MAC cipher from beginning of cipher
if [ \"$encryption\" = \"hybrid\" ] ; then
cipher=\"$(echo -n \"$cipher\" | head -c 256 )\"
elif [ \"$encryption\" = \"shared\" ] ; then
cipher=\"$(echo -n \"$cipher\" | base64 -d | tr -d '\n' | head -c 256 )\"
elif [ \"$encryption\" = \"pubkey\" ] ; then
# pubkey cipher includes a trailing newline which was stripped in
# decrypt_cipher process substitution step above
IFS= read -rd '' cipher < <( printf \"$cipher\n\" )
elif [ \"$encryption\" = \"sharedpubkey\" ] ; then
cipher=\"$(echo -n \"$cipher\" | base64 -d | tr -d '\n' | head -c 256)\"
fi
as well as many other variations (full cipher, no base 64 etc...) without success. The cipher is said to be unencrypted, so I guess it is base-64 encoded only. Would it be possible that an extra character has been added to the cipher like in the \"pubkey\" encryption scheme ?
My tests are done in a directory special remote, sharedpubkey encryption, no chunks, a single test file in the repository.
