CTemplar - Secure Email Encryption
Send unbreakable emails & protect your key professional and personal details with next-gen encryption using privacy-centric Icelandic storage.
CTemplar uses OpenPGP for end-to-end encryption of emails. It is the most widely used email encryption standard.
When a user signs up on CTemplar, its RSA private and public keys are generated using the user password as the passphrase of the private key. These keys are stored on the CTemplar server and retrieved on successful login by the user. The private key is encrypted using the user’s account password, and the user password is never sent to the server in plain form. It is hashed using a salt from the user’s username.
