| The GCM test vectors in this directory were downloaded from the NIST |
| Cryptographic Algorithm Validation Program (CAVP) website |
| (http://csrc.nist.gov/groups/STM/cavp/) on Mar 29, 2013 using the URL |
| http://csrc.nist.gov/groups/STM/cavp/documents/mac/gcmtestvectors.zip. |
| |
| The original test files are about 3 MB each, which are too big to |
| include in the NSS source tree. I observed the following patterns in |
| the test vectors: |
| 1. Taglen changes in a cycle of 7: 128, 120, 112, 104, 96, 64, 32. |
| 2. Then, AADlen changes in a cycle of 5: 0, 128, 160, 384, 720. |
| |
| To reduce the number of test vectors, I kept Taglen = 128, 96 from |
| each cycle of 7, and kept AADlen = 0, 720, 160 from each two cycles |
| of 10. |
