I have an account in A2Hosting.com, and I'm developing some functions that deal with encryption.
A2Hosting.com don't have available the function "digest()"
[code] ERROR: function digest(unknown, unknown) does not exist LINE 1: select digest('ffff', 'sha1') ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts.
Indicação de entrada : select digest('ffff', 'sha1') [/code]
I need to compile a SHA1 function, but without the digest() function, nothing done...
[code] CREATE OR REPLACE FUNCTION sha1(bytea) returns text AS $$ SELECT encode(digest($1, 'sha1'), 'hex') $$ LANGUAGE SQL STRICT IMMUTABLE; [/code]
There is a way to get this job done without the digest() function?
I need also to be able to do this select "select substr(gen_salt('md5'), 0, 10)" but there is no "gen_salt()" available...
What is my best option? To change hosting account? There is some hosting accounts with this functions available in the Postgre?
