Hello all,
I have a table with a VARCHAR column that I need to convert to a BYTEA.
How do I cast VARCHAR to BYTEA?
The following doesn't seem to work as it yields the 'cannot cast varchar to
bytea' error message:
varchar_data::bytea
On the same topic, how do I do the reverse, that is,
Hello,
How do you encrypt() & decrypt() data of types INT4 or DATE?
The PGCrypto methods encrypt() and decrypt() each take BYTEA as input:
i.e.,
encrypt( data::bytea, key::bytea, type::text)
decrypt( data::bytea, key::bytea, type::text)
So how do you convert INT4 and DATE data into BYTE
Hello there,
What's the preferred and most efficient way to obtain PGCrypto encrypted
data from a plpgsql function?
1. Imagine the following simple table:
CREATE TABLE crypto (
pid SERIAL PRIMARY KEY,
title VARCHAR(50),
crypted_content BYTEA
);
2. Now insert the following 3 rows
n's RETURN declaration
is logical... but now I know that if want a VARCHAR, I gotta manipulate it
as a TEXT within my function when using PGCrypto. Any idea why?
Thank again, Jim!

I would change the return type to TEXT, I believe your original example had
it as a varchar and
content,
decode(''password''::text, ''escape''::text), ''aes''::text),
''escape''::text ) = _crypt_data;
RETURN ( ret );
END;
' LANGUAGE 'plpgsql';
Thanks, all. This postgresql forum rocks!
Hello there,
I have a View with a Delete rule and I would like the Delete rule to call a
function (and pass-in a few of the the underlying View's/Table's column
values). How do you do this?
When I do it, I keep getting the following error:
ERROR: function expression in FROM may not refer to ot
ding answers to questions like mine below. Much better than the
Hackers or Admin forums it seems.
Thanks all!

Hello there,
How do you secure a VIEW so that only certain users may use it?
Let's say you have a table that has a BYTEA column that holds (pgcrypto)
encrypted data; and you have a VIEW on the aforementioned table that returns
the decrypted contents of the BYTEA column.
How do you secure this V
Hello all,
I'm looking for advice on real-world PGCrypto usage.
I understand how to programmatically encrypt/decrypt data with PGCrypto --
no problem.
My question is:
What is the best way to update massive amounts of *existing* encrypted data
with a new encryption passphrase, assuming you k
Thank you, Joe.
Your solution provided below works great. Much better/simpler than my
original approach. You rock!
