EDI ANSL X12

EDI ANSI X12 stands for Electronic Data Interchange, American National Standards
Institute X12. The EDI ANSI X12 standard was developed to govern the use of EDI
to exchange information electronically between businesses. The EDI ANSI X12
standard is most prevalent in the United States and has counterparts used in other parts

of the world, like the UN/EDIFACT standard that is the equivalent of EDI ANSI X12
outside the US. Any EDI transaction sent in the United States must conform to the
EDI ANSI X12 standard in order to be "EDI Compliant" and while there are a number
of EDI ANSI X12 compliant software translators, not all EDI ANSI X12 software is
created equal.

Difference between AES and DES ciphers

AES and DES are both examples of symmetric block ciphers but have certain
dissimilarities.

AES DES

AES stands for Advanced Encryption Standard DES stands for Data Encryption Standard

Date of creation is 1999. Date of creation is 1976.

Key length can be of 128-bits, 192-bits and 256-
bits. Key length is 56 bits in DES.

Number of rounds depends on key length : DES involves 16 rounds of identical
10(128-bits), 12(192-bits) or 14(256-bits) operations

The structure is based on substitution-
permutation network. The structure is based in festal network.
