CDSA stands for Common Data Security Architecture. It provides a security framework that includes cryptographically signed modules to present an abstracted unified API to the application developer to perform cryptographic and security related operations. It also includes hardware support for cryptographic tokens and biometric devices, such as thumbprint scanners. Intel has implemented the CDSA 2 specification and released it as open source.
OpenSC provides a set of libraries and utilities to work with smart cards. Its main focus is on cards that support cryptographic operations, and facilitates their use in security applications such as authentication, mail encryption, and digital signatures. OpenSC implements the PKCS#11 API so that applications supporting this API (such as Mozilla Firefox and Thunderbird) can use it. On the card, OpenSC implements the PKCS#15 standard, and aims to be compatible with every software/card that does so.
TPassguard is designed for working with Unix systems or the Web, where you need to remember a number of passwords. This program manages passwords in an encrypted file, so that you only have to remember one. It uses the PassGuard Framework and can be interfaced with any kind of encryption via a plugin system.
The PassGuard suite is a set of software that manages your passwords encrypted in a file. You just have to remember one, and different encrypted file formats are supported via plugins. The PassGuard gpasman plugin is the plugin that manages gpasman files encrypted with the RC2 algorithm.
twocrypt (2c) is a tool for the ultra-paranoid, providing a traditional crypto, but also an option of deniable (subpoena-proof) encryption. It encrypts one or two files at once. Each file can be recovered with its respective passphrase, but the presence of more than one file cannot be demonstrated, and the presence of this option alone should not be a credible argument for data hiding.
GPassguard is a GTK+ frontend to the *PassGuard suite, which manages passwords in an encrypted file so that you only have to remember one. It uses the PassGuard Framework and can be interfaced with any kind of encryption via a plugin system. It allows you to copy passwords to the clipboard.
The PassGuard suite is a set of software that manages passwords encrypted in a file. Users just have to remember one password, and different encrypted file formats are supported via plugins. The PassGuard FPM plugin is a plugin that manages Figaro's Password Manager files encrypted with the Blowfish algorithm.
