Free pkcs software for windows

PKIBlackbox is a comprehensive component collection that adds Public Key Infrastructure (PKI) support to your Delphi, C++Builder or Kylix application. PKI includes X.509 certificates, certificate requests, certificate revokation lists, certificate storages etc. .
Main PKIBlackbox functions are:
* generate and validate certificates
* create and process certificate requests
* manage Certificate Revokation Lists
* import and export certificates in DER, PFX and PEM formats
* encrypt/sign and decrypt/verify files in PKCS#7 format
PKIBlackbox supports Windows Certificates and Windows Certificate Storages. PKIBlackbox lets you manage certificates, stored on CryptoCards and USB CryptoTokens.
This is VCL edition, which can be used with Delphi 4-7 and 2005/Win32, C++Builder 4-6 and Kylix 2-3.

ACert Viewer Plus is a free Firefox extension that adds two options to the certificate viewer in Firefox or Thunderbird ACert Viewer Plus is a Firefox extension that adds two options to the certificate viewer in Firefox: an X.509 certificate can either be displayed in PEM format (Base64/RFC 1421, opens in a new window) or saved to a file (in PEM or DER format - and PKCS#7 provided that the respective patch has been applied).
Additionally, the Tools menu is extended by an entry for direct access to the certificate manager (including a keyboard shortcut).
As of release 1.0 , the XPI file of this extension is signed. Its signature will successfully verify under Firefox or Thunderbird if the "Builtin Roots Module" is available in its standard configuration. If you get an error like "could not install the file ... because: Signing could not be verified", its either due to the fact that somebody tampered with the file (let me know where exactly you got it from, in this case) - or that you tweaked the trust settings of the built-in certification authorities.
In the latter case, I assume that youre also savvy enough to figure out what trust anchor needs to be re-enabled in order to make the verification succeed again... (or how to rip the signature out of the file, otherwise) ;-)
System requirements:
- Firefox: 1.5.0.4 ? 3.0.0.*

XCA will allow you to create and manage X.509 certificates, certificate requests, RSA and DSA private keys and CRLs XCA will allow you to create and manage X.509 certificates, certificate requests, RSA and DSA private keys and CRLs.
Everything that is needed for a CA is implemented. All CAs can sign sub-CAs recursively. These certificate chains are shown clearly.
For an easy company-wide use there are customiseable templates that can be used for certificate or request generation. All crypto data is stored in a local and portable file format.
Xca supports next to the usual PEM and DER format of certificates the import and export of PKCS#12 (aka *.pfx) files and the Certificate import from PKCS#7 files.
Certificates can be created by self signing it, by signing it by an other (usually CA) certificate or by signing a PKCS#10 request. Netscape SPKAC is supported since version 0.4.6.
The validity dates and x509.v3 extensions can be adjusted to fit ones needs. The use of multiple certificates in CA chains is supported and a tree view of the certificates reflects the dependencies.
The application takes care to not create duplicate certificates by checking the serial number(s) on import and creation of certificates.
Certificate Templates can be used to preset the input dialog with reasonable values and to simplify the process of creating certificates and requests.
Issued certificates can be revoked and the revokation list can be created and exported. External revokation lists can be imported and examined.

Javasign is a software written in java able to produce a digital signature and a timestamp on a document, using a smart card Javasign is a software written in java able to produce a digital signature and a timestamp on a document, using a smart card or a token file in p12 format.
Javasign works with ISO 7816-4 compliant smart cards. It uses encryption and decryption functions based on PKCS #15 compliant cards.
Javasign has two modes of operation:
1) smart card: performs digital signature/verification operations using the functions on the card.
It can be configured to use the cryptoki library given by the card vendor, or an internal java driver that performs low level apdu commands.
2) p12 file: uses an external file in standard p12 format to keep private keys and certificates
Javasign can verify the associated certificate and check if its been released by a trusted CA.
Moreover the certificate is checked against the CRL, by downloading it from the CA site, using http protocol or ldap protocol.
Javasign is based on Italian CNS specification for identity card (Carta Nazionale dei Servizi).

BCArchive creates encrypted archive and allows you to e-mail it to your friend BCArchive software you may encrypt and compress a group of files/folders
to an encrypted archive (i.e. single file).
With BCArchive you may store all you confidential files in archives that will allow you to access them whenever you need. All of your files are being encrypted and therefore protected against unauthorized access.
You may create self-extracted program containing encrypted archive and e-mail it to your friend. He/she will receive this archive and can read your files, either via knowing correct password or via using public/secret key technology.
All already generated public and secret keys used in other programs can be also used in BCArchive to create encrypted archive and e-mail it to desired recipient.
BCArchive uses strong symmetric encryption algorithms such as Blowfish, IDEA, Triple-DES, CAST5; secure hash algorithms: SHA-1, MD5, RIPEMD-160; asymmetric (public/secret key) algorithms such as RSA, ELGamal/Diffie-Hellman; conforms to specifications PKCS #5, PKCS #12, X.509.
BCArchive is convenient software product providing you with strongest encryption technology and ability for efficient management of sensitive data.
Main function of the BCArchive is to provide the user with a tool for compressing and encrypting files and/or folders to a single archive file.
From one hand, BCArchive provides a number of ways to create such an archive file and put sensitive data into it, including Windows shell extension commands and support of drag-and-drop operations. From the other hand, BCArchive utilizes strong and proven encryption algorithms and standards to provide high security level for the data stored inside the compressed files.
BCArchive utilizes the following encryption algorithms, standards and specifications:
- Symmetric algorithms: Blowfish, IDEA, Triple-DES and CAST5.
- Secure Hash Algorithms: SHA-1, MD5 and RIPEMD-160.
- Asymmetric (public/secret key pair) algorithms: RSA, ElGamal / Diffie-Hellman.
- Specifications for public/secret key pair format: PKCS #12, X.509.
- PKCS #5 (recommendations for the implementation of password-based cryptography).
- RFC 2440 specifications for session keys encrypted by symmetric or public key encryption algorithms.
Main features:
- Create compressed and encrypted archive file protected by password.
- Create compressed and encrypted archive file encrypted by public key of another user.
- Add a number of passwords to existing archive file.
- Add a number of public keys to existing archive file so that a number of users can decrypt the archive.
- Generate new or use existing secret/public key pairs in PKCS-12/X.509 format.
- Compress and encrypt data to self-extracted executable program. The user can run the program on computer where BCArchive is not installed and get the data extracted.
System requirements:
- Minimum 7 MBytes of free HDD space to install and run the BCArchive software.
Version restrictions:
- Compressed and encrypted archive file created by the BCArchive software can store up to 2 Terabytes not compressed data.
- Self-extracted archive file contains all executable code necessary to extract data stored inside the archive. The code includes correspondent symmetric encryption algorithm, public/secret key algorithm, secure hash algorithm implementations as well as the code to uncompress data. Size of the code is about 130 Kbytes, hence minimum size of self-extracted archive is about 130 Kbytes. The limitation does not concern regular (not self-extracted) archive files.

Store images and other files in encrypted archives and view them conveniently. KittyXplorer combines the safety of strong encryption with an interface similar to the Windows Explorer and with a build-in image viewer. Files can be encrypted individually, or placed inside encrypted archives that safely hide any file information, such as names, size, and data.
