Hi,
while playing with pgcrypto I ran into a strange issue
(postgresql 9.5.3 x86 on Windows 7)
Having a table with a field
dateofbirth text
I made the following sequence of SQL commands
update tbl_p set dateofbirth = pgp_sym_encrypt('2018-06-21',
'AES_KEY') where codguid = '00000001-0001-0001-0001-000000000001';
OK
select pgp_sym_decrypt(dateofbirth::bytea, 'AES_KEY') as datanasc
from tbl_p where codguid = '00000001-0001-0001-0001-000000000001'
'2018-06-21'
select * from tab_paz where pgp_sym_decrypt(natoil::bytea, 'AES_KEY')
= '2018-06-21'
You switched gears above.
What is the data type of the natoil field in table tab_paz?
Sorry, just a typo... natoil is, actually dateofbirth, so it's text.
You can read it as
select * from tbl_p where pgp_sym_decrypt(dateofbirth::bytea, 'AES_KEY')
= '2018-06-21'
Was the data encrypted in it using the 'AES_KEY'?
Yes, the command sequence is exactly reported above.
If I use pgp_sym_decrypt in a SELECT statement it's OK, but if it's in a
where clause it seems not to be working.
