Simply add that text to all your TLS
payload 😇
Maybe this could help (best on April 1st) 😛

--Yes, you have to set the security level to 0 to be able to use 1024 bit RSA and DH keys. You can use SSL_CTX_set_security_level() function to do this. Of course you should do it only for legacy purposes as such short keys do not provide sufficient security protections.
