Attached Key Sample Files

See Key import files from USB - sample files+.

Attached key sample files use the following 3TDEA KEK:

{0x02, 0x25, 0x48, 0x67, 0x89, 0xAB, 0xCD, 0x01, 0x01, 0xDC, 0xBA, 0x98, 0x78, 0x53, 0x34, 0x17, 0x12, 0x23, 0x34, 0x41, 0x32, 0x45, 0x67, 0x78}

Common to All Files

• Files are plain text.
• Comment lines start with # and are ignored.
• Empty lines are ignored.
• Each line contains exactly one key entry.
• Files can be prepared in Windows or Linux.
• Each line ends with a newline.

Cryptograms

• If the KEK is AES, then KEY cannot be 3TDEA.

  • Padding scheme is unknown.
• IV is zero (ASCII zero).

  • TDEA example: "\x30\x30\x30\x30\x30\x30\x30\x30".
• CBC mode.

KCV

• Legacy for TDEA: 3 bytes (6 HEX chars).
• CBC-MAC for AES: 5 bytes (10 HEX chars).
