Thanks a lot. I am using F5 BIGIP iRules, which is a restricted TCL, and which provides the following functions: crc32 - Returns the crc32 checksum for the specified string. md5 - Returns the RSA MD5 Message Digest Algorithm message digest of the specified string. sha1 - Returns the SHA version 1.0 message digest of the specified string. sha256 - Returns the Secure Hash Algorithm (SHA2) 256-bit message digest of the specified string. sha384 - Returns the Secure Hash Algorithm (SHA2) 384-bit message digest of the specified string. sha512 - Returns the Secure Hash Algorithm (SHA2) 512-bit m I'll check with the vendor which is cheapest CPU and performance wise, as they might be using hardware acceleration for these things. Thanks a lot, Mohamed. _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
