The encType field is separated from the rest of the string using a period (. The ciphertext, iv and mac fields are encoded using base64.Īll of my secrets appear to have all of these fields present, I imagine that secrets produced with an older client may not. mac - the message authentication code (optional).iv - the initialization vector (optional).A numeric ASCII representation of the EncryptionType enum.encType - the encryption type used for this secret.Anatomy of a Secret ¶įirst of all, we have to understand what a Bitwarden secret looks like - they refer to them as a " CipherString".įundamentally, a CipherString contains the following information: For this reason, I am reviewing the command line interface sources - the server has nothing to give on this front. You are able to get hold of the encrypted secrets with suitable access to the MSSQL server, and the secrets are held by clients in the same state. Additionally, I am not a cryptographic expert, so this should not be considered a review for strength or integrity. I am working with my secrets, and I obviously know my passphrase - this is not a demonstration of a weakness or vulnerability. I've set out to understand how Bitwarden keeps secrets, with an end goal of decrypting them.
