Using Custom Library Tool for Intel® Cryptography Primitives Library

Using Custom Library Tool for Intel® Cryptography Primitives Library#

With the Custom Library Tool, you can build your own dynamic/shared library containing only the Intel® Cryptography Primitives Library functionality that is necessary for your application.

The use of custom libraries built with the Custom Library Tool provides the following advantages:

  • Package size. Your package may be much smaller if linked with a custom library because standard dynamic/shared libraries contain all optimized versions of Intel® Cryptography Primitives Library functions and a dispatcher. The following table compares the contents and size of packages for an end-user application linked with a custom dynamic/shared library and an application linked with the standard Intel® Cryptography Primitives Library dynamic/shared libraries:

    OS

    Application linked with custom dynamic/shared library

    Application linked with Intel® Cryptography Primitives Library dynamic/shared libraries

    Windows*
    crypto_test_app.exe
    crypto_custom_lib.dll

    Package size: 0.1 Mb
    crypto_test_app.exe
    ippcp.dll

    Package size: 7.4 Mb

    Linux* OS
    crypto_test_app
    crypto_custom_lib.so

    Package size: 0.1 Mb
    crypto_test_app
    libippcp.so

    Package size: 9.0 Mb

  • Smooth transition to a higher version of Intel® Cryptography Primitives Library. You can build the same custom dynamic/shared library from a higher version of Intel® Cryptography Primitives Library and substitute the libraries in your application without relinking.

Note

The current Python* version of the Custom Library Tool supports the host-host configuration only, the host-target configuration is currently not supported.
