What is a .Keychain file?
A .keychain file is an Apple Keychain storing passwords and certificates.
- Did you know
- The Keychain is where macOS safely keeps your saved passwords and keys.
- Apple’s keychain idea dates back to the PowerTalk mail engine in the early System 7 era, long before Mac OS X revived it.
- Each macOS user has a default “login” keychain that unlocks automatically with their account password.
- What Analyser reads
- Identify and read more security and forensics files: OpenPGP messages/keys/signatures (.pgp/.gpg/.sig - armor type, packet walk, key algorithm and user ID, secret-key warning), YARA rules, Snort/Suricata IDS rules, STIX/OpenIOC threat intel, Fiddler captures (.saz), 1Password exports (.1pux), Apple Keychain, KeePass 1.x (.kdb), Microsoft keys (.pvk) and AFF/AFF4 forensic images.
- Depth of analysis
- .Keychain 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 .Keychain file
- Drag a .Keychain 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.
