EMV Tools

Symmetric Crypto

Tools for symmetric key cryptography (e.g., AES, DES). Provide input fields for plaintext/ciphertext, key, IV, and options for algorithm, mode, and padding.

RSA

Perform raw RSA operations. All inputs and outputs are ASCII HEX. The exponent field is used for both public (e) and private (d) exponents. Ensure your data, when converted to a number, is less than the respective modulus.

Hex Manipulator

Upload a binary file to view its content as a continuous block of ASCII HEX. Click inside the text area to see cursor offsets. You can edit the text to add formatting (spaces, newlines).

Cursor: Char 0 | Byte 0
Selected: 0 Chars | 0 Bytes

Hash Calculation

Calculate cryptographic hashes. Input data as ASCII HEX.
