Late last year (2022) I encrypted a file using OpenSSL using terminal on my Mac with a very simple openssl enc
command and was able to decrypt using this command:
openssl enc -d -aes-256-gcm -in filename.lock -out filename.unlock
Fast forward to now (early 2024), it appears that when openssl updated I now receive an error message of "AEAD ciphers are not supported".
After much research, I believe I understand why I'm getting this message, but not sure what to do.
Is there a way to downgrade back to an older version of openssl? I would really like access back to this file. Thank you in advance for your help!
Update: Something I found in the comments of another post on Stack Overflow may be a similar situation. The user said they were:
"I am using OpenSSL version of OpenSSL 1.1.1c and by using LibreSSL I am able encrypt and decrypt"
