About AES Encryption

AES (Advanced Encryption Standard) is a symmetric block cipher chosen by the U.S. government to protect classified information. It is implemented in software and hardware throughout the world to encrypt sensitive data.

Key Features:

Supports key sizes of 128, 192, and 256 bits
Operates on 128-bit blocks of data
Supports multiple modes of operation: ECB, CBC, CFB, OFB, and CTR

EMV Decoder tools perform all calculations client-side for maximum security.
No sensitive data is ever transmitted to our servers.
