# PGP PGP (Pretty Good Privacy) is an encryption standard used to secure data through cryptographic methods. It ensures the confidentiality and integrity of sensitive files and communications by encrypting them with public and private keys. Frequently used in secure email communication and file encryption, PGP is widely adopted in industries that handle sensitive or regulated information, such as finance, healthcare, and legal services. Frends can integrate with PGP by automating encryption and decryption tasks within workflows. By combining Frends and PGP, organizations can ensure secure data exchange between systems, partners, or customers while maintaining compliance with data security regulations. Frends workflows can include operations like encrypting/decrypting files, key management, and transferring encrypted data seamlessly across systems. ## Use cases Below you will find typical use cases for PDF integrations and how they are implemented in Frends. ### Encrypt a file By using the [`Encrypt`](https://docs.frends.com/tasks/tasks/pgp/encryptfile) task, we can encrypt a file with a public key or private key.
