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).
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.
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
EBCDIC data is encoded on 8 bits (256 possible codes).
Any reference to IBM or variants of the ASCII table are clues.
EBCDIC encoding was created in the late 1950s.
