Files.com encrypts data in transit for every supported protocol and supports file-level encryption with GPG (PGP) for data at rest. This section covers the protocols Files.com encrypts, the cipher suites and certificates that govern those connections, and the GPG features that handle encrypted files independent of transport.

Encryption In Transit

Files.com encrypts network traffic for supported protocols, and the protocol determines the mechanism. HTTPS and FTPS use TLS. SFTP uses SSH. Protocol setup details live under Services.

Ciphers And Compatibility

Cipher support affects which clients can connect and the overall security posture of the site. Some environments require legacy options for compatibility with older clients; use them only when a current client cannot negotiate a modern suite. See Ciphers for supported cipher suites.

TLS/SSL Certificates

TLS relies on certificates for authentication, and certificate choices affect which clients trust the connection. See TLS/SSL Certificates for certificate handling and configuration.

File-Level Encryption With GPG (PGP)

GPG encrypts and decrypts files at rest, independent of transport security, and is compatible with PGP. Use it when files need to remain encrypted after they arrive on the destination. See GPG (PGP) for keys, encryption, and decryption.

Automatic Key Management

Some workflows require managed key rotation and handling. Files.com supports this for GPG. See Automatic Key Management for the supported behavior.

Example Use Cases

Customers apply Files.com encryption features for legacy SFTP client compatibility, TLS handshake and trust troubleshooting, custom domains with customer-managed certificates, PGP/GPG exchange with external partners, and confirming the cipher a client actually negotiates. See Encryption Use Cases for examples of each.
