Acid Cryptofiler is a software designed by the department for "control of information" of the French General Directorate of Armament (Direction générale de l'armement).[1]

Acid Cryptofiler is based on the integration of government cryptographic libraries, including a CCSD API (CCSD means "Defense Security Cryptographic Layers"). It offers the following functions:

  • Asymmetric encryption (cf. public-key cryptography) in archive format (multi-file, multi-recipient) called Acid Archives.
  • Volume encryption (containers) in symmetric mode and asymmetric mode.

Acid Cryptofiler is delivered with a directory function to file public keys, that is compliant with LDAP and Active Directory.

A bunch file contains all public keys held by a user. A user can belong to different cryptographic domains (a domain is a CCSD library and a set of cryptographic parameters). Private keys are also stored in a bunch file.

The keys are generated by a centralized office under the responsibility of the chief information security officer. Before a user is given a key (or a pair of keys), he/she must be trusted by the centralized office. In France, Acid Cryptofiler does not fit for defense classified information.

Acid Cryptofiler was designed and developed by two military engineers of the Direction générale de l'armement. It has been delivered since 1999 (version 4, 5, and 7). It runs on Microsoft Windows.
