SAP released the new B2B Add-On package couple of months back and we have some really informative and descriptive articles about the features and configurations. I must admit that SAP has done a really nice job in terms of documentation available with the download and here on SCN.
We got lucky with the timing and got a chance to use this Add-On to achieve encryption while communicating with external vendors. Although the implementation process went pretty well, there were still some learning which I wanted to share through this blog.
Several Encryption algorithms are supported by PGP module. Here is the list: AES_128, AES_192, AES_256, BLOWFISH, CAST5 (default), DES, 3DES. For the Encryption, it is a pre-requisite to have you the keys generated and stored. The guide referred above have links to create the keys as well. I have some observations based on the documentation:
PGP supports three compression alogirthms - ZIP, ZLIB and BZIP2. ZLIB is the default algorithm used if you don't specify the parameter applyCompression in the module chain. We performed some tests to evaluate these compression algorithms. We encrypted a text file 169 MB in size using PGP modules and here are the results.
| Original Size | Compressed Size | Percentage Of Original |
BZIP2 | 169,047,219 | 36,604,303 | 21.7% |
ZLIB | 169,047,219 | 50,227,869 | 29.7% |
ZIP | 169,047,219 | 50,227,861 | 29.7% |
The observations were:
In all, I like the PGP adapter module and definitely the fact that it is free. :smile:
I would like to thank my colleague jean.patoine who helped me throughout.
