The OpenPGP module for EFT employs industry-standard OpenPGP technology to safeguard data at rest. The OpenPGP module uses a combination of strong public-key and symmetric cryptography to provide secure data exchanges for electronic communications and data storage. Encrypted file transfer provides confidentiality, key management, authentication, and digital signatures. OpenPGP uses a public key and a private key to encrypt data and maintain security.

How Encrypt/Decrypt Works in EFT

In EFT, the OpenPGP encryption/decryption process is directed by Event Rules that specify how data files are treated in a particular context. When a selected event occurs (e.g., a file is uploaded to the server), if the specified condition exists (e.g., the user is a member of group A), then the selected actions occur (e.g., encrypt the file). OpenPGP encryption is available when a file is uploaded, when a log file is closed and a new log initiated, and when an event occurs according to a schedule.

What is a Key Pair?

The public key and the private key are considered a key pair. The key pair is stored on the OpenPGP Key Ring in EFT and is the management tool for public keys and key pairs. The OpenPGP Key Ring contains all key information and allows import, export, creation, and deletion of keys. Key pairs are created using the OpenPGP Key Generation wizard in EFT. A message encrypted with a recipient’s public key cannot be decrypted by anyone except the recipient possessing the corresponding private key.


  • Globalscape EFT employs industry standard OpenPGP (based on the open source implementation of Pretty Good Privacy) technology to safeguard data at rest.
  • EFT adheres to the OpenPGP standard and is RFC 2440 compliant.
  • In contrast to symmetric encryption technologies that rely on a single password or shared secret for encryption and decryption. OpenPGP uses a public/private key pair and a password.
