Unable to decrypt a mail


A mail adressed to XXXX@mlalerte.org is encrypted and cannot be decrypted. The mail was encrypted with a public key found in hkps://keys.openpgp.org but the secret key and the password have since been lost.

When in Thunderbird (version 78+), the incorrect key can be deleted using Tools > OpenPGP key manager.


Assuming your contact sent you their public key and you saved it in a file, it can then be imported from within the OpenPGP Key Manager with File > Import Publi Key(s) From File
