Implementations

impl EncryptHelper

pub async fn new(context: &Context) -> Result<EncryptHelper>

pub fn get_aheader(&self) -> Aheader

pub fn should_encrypt( &self, context: &Context, e2ee_guaranteed: bool, peerstates: &[(Option<Peerstate>, String)], ) -> Result<bool>

Determines if we can and should encrypt.

For encryption to be enabled, e2ee_guaranteed should be true, or strictly more than a half of peerstates should prefer encryption. Own preference is counted equally to peer preferences, even if message copy is not sent to self.

e2ee_guaranteed should be set to true for replies to encrypted messages (as required by Autocrypt Level 1, version 1.1) and for messages sent in protected groups.

Returns an error if e2ee_guaranteed is true, but one or more keys are missing.

pub async fn encrypt( self, context: &Context, verified: bool, mail_to_encrypt: PartBuilder, peerstates: Vec<(Option<Peerstate>, String)>, compress: bool, ) -> Result<String>

Tries to encrypt the passed in mail.

pub async fn sign( self, context: &Context, mail: PartBuilder, ) -> Result<(MimeMessage, String)>

Signs the passed-in mail using the private key from context. Returns the payload and the signature.
