I've successfully implemented the mail_crypt plugin on v2.2.27 and it's working like a champ, but some of our administrative operations require access to Maildir messages in plaintext.
I've found numerous threads detailing help with mail_crypt setup, but none of my research has yielded a method of decrypting the stored messages. Relevant plugin config: mail_crypt_curve = prime256v1 mail_crypt_global_private_key = <pirvkey> mail_crypt_global_public_key = <pubkey> mail_crypt_save_version = 2 Method I attempted for manual decryption is listed below: openssl pkeyutl -derive -inkey mailcrypt.key -peerkey mailcrypt.pub -out shared_secret.bin openssl enc -aes256 -base64 -k $(base64 shared_secret.bin) -d -in test.enc -out test.txt Openssl reports an error reading the input file, but it isn't permissions related. I started looking for the encryption/decryption method in the source but figure it's worth seeing if there's some existing methodology I can employ here. Appreciate any feedback.
