Answers to Questions (FAQ)
What is EBCDIC encoding? (Definition)
Extended Binary Coded Decimal Interchange Code (EBCDIC) is an 8-bit computer character encoding created by IBM.
Used in punch cards (from IBM with 80 columns), the character table has 256 codes and each code corresponds to one character (but not the same as ASCII).
How to encrypt using EBCDIC cipher?
To encode in EBCDIC from a binary message (this may be ASCII-encoded text), each 8-bit group is then encoded via the EBCDIC table.
Each ASCII code corresponds to an EBCDIC code and conversely, noting the ASCII and EBCDIC codes with a value between 0 and 255, then there is an equivalence that allows the encryption.
The encoded message can then be displayed via the ASCII table (resulting in an often unreadable encrypted message).
Example: The 5 characters' DCODE 'are coded 68,67,79,68,69 in ASCII but 196,195,214,196,197 in EBCDIC
How to decrypt EBCDIC cipher?
How to recognize EBCDIC ciphertext?
EBCDIC data is encoded on 8 bits (256 possible codes).
Any reference to IBM or variants of the ASCII table are clues.
When was EBCDIC invented?
EBCDIC encoding was created in the late 1950s.
