Does this section of code trigger a warning every time a caller is using SHA1 crypto? Is it safe to comment this section out so that I don't see the messages in my logs/console? I understand that SHA1 has security vulnerabilities and want to be sure that this warning message is only indicating that. More for my learning than anything else. Absolutely in love with FreeSWITCH, thanks guys! Hoping to contribute wherever I can!

Thanks,
