Re: [general] Encrypting/Decryption

Hi Venktesh,

Following is small test case:
======================

leon=# create table demo(pw bytea);
CREATE TABLE
leon=# insert into demo(pw) values ( encrypt( 'data', 'key', 'aes') );
INSERT 0 1
leon=# select decrypt(pw, 'key', 'aes') FROM demo;
decrypt
------------
\x64617461
(1 row)

leon=# select convert_from(decrypt(pw, 'key', 'aes'), 'utf-8') FROM demo;
convert_from
--------------
data
(1 row)

BTW, please think carefully about whether PgCrypto is really the right
choice. Keys in your queries can be revealed in pg_stat_activity and the
system logs via log_statement or via crypto statements that fail with an
error.

You can follow the below link for more information regarding the encryption
options:

Hope this helps.

Thanks & Regards,
