Welcome to the conpal LAN Crypt 2Go FAQ page.
Files encrypted with conpal LAN Crypt 2Go can be recognized by the file extension .pcrypt. On systems where conpal LAN Crypt 2Go is installed, encrypted files are easily recognizable by the LAN Crypt 2Go icon.
You can encrypt any file with a file size of up to 2 GB.
No, conpal GmbH can neither view the file nor the password. A decryption is not possible for us.
No, conpal GmbH can neither see the file nor the password. A decryption is not possible for us.
Is my file transferred to the server of conpal GmbH or to the server of third parties when using the web service portal?
No, the file will not be transferred at any time. It remains on your computer. The encryption is done by a program component of the website, which is executed directly in your browser, on your end device. This program component does not transmit any data to the server, neither data nor password.
Yes, the protection remains intact, even if the e-mail itself is not encrypted.
Yes. The protection remains intact. The cloud operator does not gain access to the plain text version of the file, but can only view the encrypted version, which is useless to him.
To do this, choose a suitable way that is as separate as possible from the one you use to send the file. So you could send the password by messenger, the file by email. Sending the password verbally, by phone or by mail is also a good way to avoid compromising the protection of your file. Avoid sending the password and the file in the same message (such as a single email) – this lowers the level of protection because a potential attacker would only need to intercept a single message to gain access to the file.

Under Windows it is possible to integrate conpal LAN Crypt 2Go into Outlook. Whenever you now send an attachent in an email or calendar invite to a recipient who is outside your organization, you will receive the recommendation to encrypt the file. To do this, you simply set the password, the rest happens automatically. The encrypted version of the file is then attached. Of course, you can also reject encryption, in which case the file will be attached as usual. In addition, they can also manually trigger the encryption of attachments if necessary. In this way, they can ensure that data is also transferred securely within their organization.
If the email goes to a recipient with whom a password has already been exchanged, conpal LAN Crypt 2Go offers to use the same key from the “Key Ring” password store.

What is the difference between files encrypted with conpal LAN Crypt 2Go and files encrypted with the enterprise solution conpal LAN Crypt?
conpal LAN Crypt 2Go uses the same encryption method as the Enterprise solution. The difference is in the keys used. With conpal LAN Crypt 2Go these are securely derived from the passwords entered by the user. The Argon2 password hashing method is used. With the Enterprise solution the keys are generated by a random number generator.
It is possible to import password-based keys into the conpal LAN Crypt enterprise solution admin via an API interface and thus make them available to other users.
