In Texis version 8 and later, SQL (and Webinator/Appliance) passwords are more secure: they are no longer limited to 8 bytes, various algorithms have been added (multi-round SHA-512 etc.), and more characters are supported (any non-nul byte) if passed as a parameter. User names are also no longer limited to 20 bytes. See notes under [Texis] Default Password Hash Method for more details.
Caveat: Passwords created by Texis version 8 may not be accessible by earlier Texis versions, as they do not support the newer hash methods. The OpenSSL libraries shipped with Texis are now used for all password hashing, so they are required by Texis, instead of being somewhat optional as in previous versions (e.g. largely for https fetching).
