EFT Calculator

EFT Calculator is a lightweight software application developed specifically for helping you conduct cryptographic tasks used in electronic funds transfer programs. For example, it comes with support for DES/3DES cryptographic operations.
The tool is available for download on Windows XP, Vista, and 7. In order to run it correctly and avoid all sorts of compatibility issues, you need to deploy Microsoft .NET Framework 4.0 on the target computer.

Clean feature lineup

You are welcomed by a well-organized suite of features. A multi-tabbed environment is implemented for each supported cryptographic operating so you can easily tweak the dedicated parameters. Online documentation is available in case you have extra questions regarding the program’s features.

Work with various cryptographic functions

EFT Calculator gives you the possibility to carry out DES/3DES operations. You just need to input details about the data and key, perform encryption/decryption tasks, as well as calculate the key check value and find out the parity of the key used.
In addition, you can force odd or bit parity on the result, and employ bitwise AND/OR/XOR operations between the data and key.
You are allowed to calculate a clear and encrypted PIN block and find out the PIN from an encrypted PIN block, as well as identify the Card Verification Value for specific parameters (service code, card PAN, card expiration date, and CVK pair).
Other important calculations worth being mentioned enable you to calculate a Visa PIN Verification value, compute and verify a PAN check digit, as well as store and reuse cryptographic keys.
Tests have shown that EFT Calculator executes calculations very quickly and without errors. It remains light on system resources so the overall performance of the computer is not hampered.

Final remarks

To sum things up, EFT Calculator comes bundled with several smart features for helping you compute and analyze various cryptographic parameters, and can be tweaked by beginners and professionals alike.
