What type of file must be uploaded in the Password Bank when selecting Email Encryption Certificate?

When selecting the Email Encryption Certificate, the file that must be uploaded to the Password Bank is in the PFX or P12 format. These file types are specifically designed to store private keys and their associated certificates in a secure manner.

PFX (Personal Exchange Format) and P12 files are widely used for exchanging public and private key pairs securely, particularly when dealing with email encryption. They bundle both the certificate and the private key into a single file, which makes it easier to manage and store credentials necessary for encrypting and signing emails. This format is particularly important for maintaining the integrity and security of communications.

Using other file types, such as TXT, CSV, or PDF, would not be appropriate in this context as they do not support the storage of encryption certificates and keys in a secure manner. Hence, the necessity for utilizing PFX or P12 formats in this scenario.
