They are under the nss/tests/ciphers. It uses bltest. I believe it was turned off because bltest couldn't handle the corner case of leading zeros in RSA operations, which lead to periodic failures of the tests, but you can still run performance.sh yourself. I used it to test the performance of the AES-NI code when it was added. bob smime.p7s Description: S/MIME Cryptographic Signature -- dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto

I don't have any scripts for all the freebl algorithms. Do note that there are some scripts specifically for elliptic curve functions, see lib/freebl/ecl/tests/ecp_test and ec2_test with the --time option.
