Hi,
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?
Best Regards,
