What is a .ENC file?
.ENC is a file in the Security / keys / certs category. Analyser identifies it and reads the metadata in its header, right in your browser.
- Did you know
- The .enc extension is only a naming convention for encrypted data, not a format, so many unrelated tools use it and a file cannot be identified without knowing which one made it.
- Files written by OpenSSL default salted mode begin with the ASCII bytes Salted__ followed by an 8-byte random salt, the closest thing a raw .enc has to a magic number.
- An OpenSSL .enc records nothing about which cipher encrypted it, so decrypting one means already knowing or guessing the algorithm as well as the key.
- What Analyser reads
- Inspect security and crypto files: PEM private/public keys (RSA/EC/Ed25519, PKCS#1 vs PKCS#8, encryption), OpenSSH .pub with SHA-256 fingerprint, PuTTY .ppk, PKCS#10 CSR, X.509 CRL, PKCS#7 bundles, OpenVPN/WireGuard configs, Java KeyStores, Apple .mobileconfig/.mobileprovision, Windows .reg (with autorun flagging), and pcap/pcapng captures - warning when a private key or secret is present.
- Depth of analysis
- .ENC is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .ENC file
- Drag a .ENC file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
