The major API provided with SafeNet Product Software Development Kit conforms to RSA Laboratories' Public-Key Cryptography Standards #11 (PKCS #11) v2.20, as described in PKCS#11 Support. A set of API services (called PKCS #11 Extensions) designed by SafeNet, augments the services provided by PKCS#11, as described in Extensions to PKCS#11. The extensions to each API enable optimum use of SafeNet SafeNet hardware for commonly used calls and functions, where the unaugmented API would tend to use software, or to make generic, non-optimized use of available HSMs.
In addition, support is provided for Microsoft’s cryptographic APIs (CAPI/CNG) (see Microsoft Interfaces and Oracle’s Java Security API (see Java Interfaces).
The API is a library – a DLL in Windows, a shared object in Solaris, AIX and Linux, a shared library in HP-UX – called Chrystoki. Applications wanting to use token services must connect with Chrystoki.

Included with SafeNet Product Software Development Kit is a sample application – and the source code – to accelerate integration of SafeNet’s cryptographic engine into your system.
Note: To reduce development or adaptation time, you may re-distribute the salogin program to customers who use SafeNet Network HSM, in accordance with the terms of the End User License Agreement. However, you may not re-distribute the SafeNet Software Development Kit itself.
When RSA keys are generated, ‘p’ and ‘q’ components are generated which, theoretically, could be of considerably different sizes.
The SafeNet Network HSM allows RSA private keys to be unwrapped onto the HSM where the lengths of the ‘p’ and ‘q’ components are unequal. Because the effective strength of an RSA key pair is determined by the length of the shorter component, choosing ‘p’ and ‘q’ to be of equal length provides the maximum strength from the generated key pair. If your application is designed to generate key pairs that will be unwrapped onto the HSM, care should be taken in choosing the lengths of the 'p' and 'q' components such that they differ by no more than 15%.
Where you are generating RSA private keys within the HSM, the HSM enforces that ‘p’ and ‘q’ be equal in size, to the byte level.
The Client install includes a shim library to support PKCS#11 integration with various third-party products. You should have no need for this shim library in your development. If for some reason you determine that you need the shim, Chrystoki supports it.
