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 may be a similar situation (https://stackoverflow.com/a/60805142/23188637). 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"
