NAME
       Public_Key Application

DESCRIPTION
       The Public Key application deals with public-key related file formats,
       digital signatures, and X-509 certificates.  It handles validation of
       certificate paths and certificate revocation lists (CRLs) and other
       functions for handling of certificates, keys and CRLs. It is a library
       application that does not read or write files, it expects or returns
       file contents or partial file contents as binaries. Except for the
       functions public-key:cacerts_load/0, public-key:cacerts_load/1, and
       public-key:cacerts_get/0 that reads files.


   Supported PKIX functionality
       o   Supports RFC 5280 - Internet X.509 Public-Key Infrastructure
           Certificate and Certificate Revocation List (CRL) Profile.
           Certificate policies supported since OTP-26.2



       o   Supports PKCS-1 - RSA Cryptography Standard



       o   Supports DSS - Digital Signature Standard (DSA - Digital Signature
           Algorithm)



       o   Supports PKCS-3 - Diffie-Hellman Key Agreement Standard



       o   Supports Cryptographic Message Syntax (CMS)
           (http://www.ietf.org/rfc/rfc5652.txt) including Password-Based
           Encryption with original PKCS-5 support, but currently excluding
           offical support for most of section 10-12 (if proven useful,
           especially Attribute Certificates v2, it might be added later).



       o   Supports PKCS-8 - Private-Key Information Syntax Standard



       o   Supports PKCS-10 - Certification Request Syntax Standard



       o   Supports PKIXCMP - Certificate Management Protocol



       o   Supports PKIXCRMF - Certificate Request Message Format



   Dependencies
       The public_key application uses the Crypto application to perform
       cryptographic operations and the ASN-1 application to handle PKIX-ASN-1
       specifications, hence these applications must be loaded for the
       public_key application to work. In an embedded environment this means
       they must be started with application:start/[1,2] before the public_key
       application is started.


   Error Logger and Event Handlers
       The public_key application is a library application and does not use
       the error logger. The functions will either succeed or fail with a
       runtime error.
