Questions:

- What happens if the user password contains the character "&"? This appears to cause errors in the IP update URL, for example:

https://api.dynu.com/nic/updatehostname=mickymac.balomiri.eu&&myipv6=&myip4=&password=&1&2...

Shouldn't special characters in passwords be URL-encoded to prevent them from being interpreted as parameter separators?

2) How can one generate host-specific MD5/SHA-based passwords? And is "&" the correct separator character in this context?

Regards,
