x.509

Free command-line FTP client. All 3 SSL modes, X.509 client certificates, passive transfers and alternate ports supported. Uses same syntax as built-in "ftp.exe" client for easy drop-in replacement.

A Windows 95/NT program that allows the user to view BER/DER encoded files such as X.509 certificates and S/MIME messages.

Crypt::X509 is a Perl module to parse an X.509 certificate.

SYNOPSIS

use Crypt::X509;

$decoded = Crypt::X509->new( cert => $cert );

$subject_email = $decoded->subject_email;
print "do not use after: ".gmtime($decoded->not_after)." GMTn";

Crypt::X509 parses X.509 certificates. Methods are provided for accessing most certificate elements.

It is based on the generic ASN.1 module by Graham Barr, on the x509decode example by Norbert Klasen and contributions on the perl-ldap-dev-Mailinglist by Chriss Ridd.

Seamless integration within Windows Explorer allowsPKZIP Explorer to leverage standard file handlingfunctionality while providing advanced tools formanaging and manipulating .ZIP archives. New supportfor X.509-based digital certificates enhances thesecurity of the archive and its contents.

check_ssl_cert project is a Nagios plugin to check X.509 certificates.

It checks if the server is running and delivers a valid certificate.

It also checks if the CA matches a given pattern, and checks the validity.

abylon SELFCERT description
abylon SELFCERT - Create self-signed X.509 v3 certificates (PKCS / RSA) for private use abylon SELFCERT can create self-signed test certificates (X.509 v3) for private use. It is very easy to create and you can encrypt your data with this certificate.

Functional range: 1. Generation of self-signed X.509 v3 test certificates - 2. Automatic installation after the certificate generation - 3. Fields: Owner, Email, Country, City, Organisation and Department - 4. Key size 512 until 4096 Bits - 5. Runtime up to 9999 days (~ 27 years)

Requirements: Pentium; 64MB RAM

The Legion of the Bouncy Castle Java Cryptography API provides a lightweight cryptography API in Java. A provider for the JCE and JCA, a clean-room implementation of the JCE 1.2.1, generators for Version 1 and Version 3 X.509 certificates, generators for Version 2 X.509 attribute certificates, PKCS12 support, and APIs for dealing with S/MIME, CMS, OCSP, TSP, and OpenPGP. Versions are provided for the J2ME, and JDK 1.0-1.5.

Here are some key features of "Legion of the Bouncy Castle Java Cryptography API":

· A lightweight cryptography API in Java.
· A provider for the JCE and JCA.
· A clean room implementation of the JCE 1.2.1.
· A library for reading and writing encoded ASN.1 objects.
· Generators for Version 1 and Version 3 X.509 certificates, Version 2 CRLs, and PKCS12 files.
· Generators for Version 2 X.509 attribute certificates.
· Generators/Processors for S/MIME and CMS (PKCS7).
· Generators/Processors for OCSP (RFC 2560).
· Generators/Processors for TSP (RFC 3161).
· Generators/Processors for OpenPGP (RFC 2440).
· A signed jar version suitable for JDK 1.4/1.5 and the Sun JCE.

XySSL is a cryptographic library written in C. It currently features several ciphers (AES, Triple-DES, and ARC4), hash functions (MD{2,4,5}, SHA-1, and SHA-256), and RSA and X.509 reading support.

XySSL project also implements the Secure Sockets Layer version 3 protocol (SSLv3), as well as the Transport Layer Security version 1 protocol.

Here are some key features of "XySSL":

· AES, Triple-DES, DES, ARC4
· MD2, MD4, MD5, SHA-1, SHA-256
· HAVEGE random number generator
· RSA with PKCS#1 v1.5 padding
· SSLv3 and TLSv1 client support
· X.509 certificate reading

Whats New in This Release:

· This releases fixes several bugs and adds nine demonstration programs.

GNU Transport Layer Security Library is a library which implements a secure layer over a reliable transport layer such as TCP/IP. GNU Transport Layer Security Library implements the TLS 1.0 and SSL 3.0 protocols, accompanied with authentication methods such as X.509, OpenPGP, and SRP.

Here are some key features of "GNU Transport Layer Security Library":

· Support for TLS 1.1 and SSL 3.0 protocols
· Support for TLS extensions
· Support for authentication using the SRP protocol
· Support for authentication using both X.509 certificates
· and OpenPGP keys Support for X.509 and OpenPGP certificate handling.
· Supports all the strong encryption algorithms
· Supports compression
· Runs on most Unix platforms

Whats New in This Release:

· Support for Proxy Certificates as per RFC 3820 were added.
· The --generate-proxy option was added to certtool.
· certtool --certificate-info now prints information for Proxy Certificates.
· New APIs were added to set proxy subject names and get or set a proxy cert extension.
· Parsing of pathLenConstraints in BasicConstraints with missing CA was fixed.
· A self-test was added to test for regressions of pathLenConstraint.
· Certtool now prints times in UTC when printing certificate/CRL info.
· Importing of ASCII armored OpenPGP keys was fixed.
