Editing List of file formats (section)

== Security ==
Authentication and general encryption formats are listed here.

* OMF – OpenPGP Message Format used by [[Pretty Good Privacy]], [[GNU Privacy Guard]], and other [[OpenPGP]] software; can contain keys, signed data, or encrypted data; can be binary or text ("[[ASCII armor]]ed")

=== Certificates and keys ===
* GXK – Galaxkey, an encryption platform for authorized, private and confidential email communication{{citation needed|date=October 2017}}
* SSH – [[OpenSSH]] private key, [[Secure Shell]] [[private key]]; format generated by [[ssh-keygen]] or converted from PPK with [[PuTTYgen]]<ref name="wipo" /><ref name="leading" /><ref name="leo" />
* PUB – [[OpenSSH]] public key, [[Secure Shell]] [[public key]]; format generated by [[ssh-keygen]] or [[PuTTY]]gen<ref name="wipo" /><ref name="leading" /><ref name="leo" />
* PPK – [[PuTTY]] private key, [[Secure Shell]] [[private key]], in the format generated by [[PuTTY]]gen instead of the format used by [[OpenSSH]]<ref name="wipo" >{{cite web|url=http://www.wipo.int/patentscope/en/pct-edi/software/setup/putty-setup.html|title=Setting Up and Using PuTTY|website=Wipo.int}}</ref><ref name="leading">{{cite web |url=http://leadingedgescripts.co.uk/server-administration/how-to-convert-your-putty-ppk-private-key-to-a-normal-ssh-key-you-can-use-on-an-apple-mac/ |title=How to Convert Your Putty .PPK Private Key to a Normal SSH Key You Can Use on an Apple Mac &#124; These things are far too hard |website=leadingedgescripts.co.uk |access-date=15 January 2022 |archive-url=https://web.archive.org/web/20120711141602/http://leadingedgescripts.co.uk/server-administration/how-to-convert-your-putty-ppk-private-key-to-a-normal-ssh-key-you-can-use-on-an-apple-mac/ |archive-date=11 July 2012 |url-status=dead}}</ref><ref name="leo" >Leo Notenboom.

==== [[X.509]] ====
* CER, CRT, DER – [[Distinguished Encoding Rules]] stores certificates
* P7B, P7C – [[PKCS7|PKCS#7]] SignedData commonly appears without main data, just certificates or [[Revocation list|certificate revocation list]]s (CRLs)
* P12, PFX – [[PKCS 12|PKCS#12]] can store public certificates and private keys
* PEM – [[Privacy-enhanced Electronic Mail]]: full format not widely used, but often used to store [[Distinguished Encoding Rules]] in [[Base64]] format
* PFX – Microsoft predecessor of PKCS#12

=== Encrypted files ===

This section shows file formats for encrypted general data, rather than a specific program's data.

* AXX – Encrypted file, created with [[AxCrypt]]
* [[Encrypted Email Attachment|EEA]] – An encrypted CAB, ostensibly for protecting email attachments
* TC – Virtual encrypted disk container, created by [[TrueCrypt]]
* KODE – Encrypted file, created with KodeFile
* nSignE – An encrypted private key, created by nSign<ref name=":0" />

=== Password files ===

[[Password]] files (sometimes called keychain files) contain lists of other passwords, usually encrypted.

* BPW – Encrypted password file created by Bitser password manager
* KDB – [[KeePass]] 1 database
* KDBX – [[KeePass]] 2 database
