Bp-tools Cryptographic Calculator 20.12 Download

BP-Tools (short for "Byte Pusher Tools") is a lightweight but powerful suite of cryptographic utilities designed for Windows environments. The Cryptographic Calculator component is a Swiss Army knife for hash functions, encryption algorithms, and encoding schemes. Unlike online web-based calculators (which pose a risk of exposing sensitive data), BP-Tools runs entirely offline, making it a trusted companion for air-gapped machines and secure development labs.

Version 20.12 (released in December 2020) represents a mature build that balances stability with a broad algorithm set. It is not a cloud-based SaaS product or a bloated enterprise application; rather, it is a compact executable that prioritizes speed and accuracy.

The BP-Tools Cryptographic Calculator is a cornerstone utility for professionals in the Electronic Funds Transfer (EFT) and payment transaction industries. Developed by EFTlab, this freeware suite—specifically version 20.12—remains a highly sought-after tool for testing, benchmarking, and developing secure payment services. What is BP-Tools Cryptographic Calculator?

The suite is designed to simplify the complex cryptographic operations required for financial messaging standards like ISO 8583 and AS2805. It consists of several integrated components:

BP-CCALC (Cryptographic Calculator): The core engine for performing cipher operations, key derivations, and payment-specific calculations.

BP-EMVT: A specialized tool for EMV tag dictionary lookups, TLV parsing, and APDU response queries.

BP-HCMD (HSM Commander): A utility for querying and benchmarking Thales Hardware Security Modules (HSMs).

BP-CardEdit: A viewer and editor for Thales P3 input/output files. Key Features of Version 20.12

Version 20.12 of BP-Tools introduced or refined several critical functionalities for modern payment testing: 1. Generic Cryptography & Ciphers bp-tools cryptographic calculator 20.12 download

Symmetric Algorithms: Support for AES, DES, and 3DES with multiple modes including ECB, CBC, CFB, and OFB.

Asymmetric Cryptography: RSA certificate generation, encryption, signing, and validation.

Hashing: Extensive support for MD4, MD5, SHA-1, and the SHA-2 family (SHA-256 to SHA-512). 2. Payment-Specific Operations

PIN Processing: PIN block generation and decoding for various formats (e.g., ISO-0/Format 0) and DUKPT support. Card Security: Generation of CVV, CVV2, and iCVV.

EMV Cryptograms: Validation and generation of ARQC (Authorization Request Cryptogram) and ARPC (Authorization Response Cryptogram). 3. Key Management

Key Components: Tools to combine key parts and check key parity (odd/even).

Thales LMKs: Functionality to handle Thales Local Master Keys (LMKs), including scheme and variant applications. How to Download BP-Tools 20.12
