An End-to-End email encryption program - Protects email at rest and in motion

The free trial period is 60 days after which no sending or receiving is possible unless a license is obtained. The stored emails can be viewed also after the trial period.
Superior protection for the real world
EndCryptor protects old encrypted emails - that were copied by an adversary when they traversed the internet - also then when the adversary gets current encryption keys by hacking into user's computer.
Easy to use
No knowledge of cryptography is required. The user interface is similar to a typical email client. User's current email account is used to deliver the encrypted emails.
End-to-End Encryption
The email is encrypted at sender's computer and it can be decrypted only at true receiver's computer.
Quantum attack resistant
It may be possible that before the year 2030 there will be computers that can break current classical public keys. EndCryptor uses classical public keys and new quantum attack resistant public keys. Note that otherwise current encrypted traffic can be copied and decrypted later by quantum computers when they become reality.
State of the art cipher and public keys
The implementation of symmetric encryption and classical and quantum attack resistant public keys uses publicly available source code developed by the scientists who designed the systems.
Features:
- Both the sender and the receiver must have EndCryptor installed. An email account on email server is needed - same account (i.e. user's current email account) can be used for unencrypted emails and encrypted emails. Encrypted emails are typed using EndCryptor and they are sent and received using EndCryptor. An encrypted email is a file that is an attachment in an ordinary email. The sending and receiving is enabled by defining user's email account's settings into EndCryptor.
- The sent and received messages are stored in encrypted form on a user’s computer – the user can view their decrypted contents when correct entry password to EndCryptor has been given. The stored messages can be searched, moved between different user creatable mailboxes.
- Messages can be exported in eml format. They can be imported into email archiving solutions. They can also be viewed by many email client programs or dragged and dropped into an existing local email folder. The export feature allows the user to have a complete cleartext archive of the communication.
- The stored messages can be backed up by copying and the backups can be decrypted using a personal or a company-wide (optional) export key. EndCryptor can take a backup of the security database and restore it. That backup can be encrypted. The stored emails can also be backed up by EndCryptor immediately after they have been written to disk.
- Compression of plaintext. Required amount of random bytes are added to hide the length of this compressed plaintext - encrypted messages have different sizes even if their decrypted content is the same.
- A message may have more than one receiver. Contacts can be grouped.
- If an Internet connection is considered to be too risky then EndCryptor can be run entirely disconnected from the network. When a message is encrypted a list of its receivers can be stored in a text format, the message and the list of its recipients can be stored in user given folder. The encrypted message and this list are moved to the actual sending machine using removable media. When decryption is needed the encrypted message is delivered to the receiving EndCryptor again using removable media.
- EndCryptor can be set to monitor some user given folder for new encrypted messages.
- A custom made program can be defined so that it will do the sending of the message.
- The security database and the stored sent and received messages can be moved to removable media and accessed from it. Thus it is possible to use EndCryptor both from office and laptop computers. The size of an empty security database is about 1 MB.
