"invalid armor closing line" on inputs with specific lengths #263

Closed pennae closed 3 years ago

pennae commented 3 years ago

Environment

What were you trying to do

encrypt a thing that's 38 bytes long without having age crash because it emits invalid armored output

What happened

~ % priv=$(age-keygen)
Public key: age1c73ql4n652jz792gwfvyxx53086kyfu95p9t458pqhk8te85yg2qpwcfqg
~ % pub=$(age-keygen -y <(echo $priv))
~ % ct=$(echo "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" | age -e -a -r $pub)                                                          
~ % age -d -i <(echo $priv) <(echo $ct)
Error: invalid armor closing line: 
[ Did age not do what you expected? Could an error be more useful? Tell us: https://filippo.io/age/report ]

This is now fixed in v1.0.0-rc.2. Thank you for reporting it.

If anyone needs to decrypt a file that suffered from this issue, you can remove the empty line before the -----END AGE ENCRYPTED FILE----- line, and the file will decrypt successfully. Sorry for the bug!
