How to encrypt a column using PostgreSQL pgcrypto

10 June,2022 by Rambler

There are different types of encryption supported by PostgreSQL. If the requirement is to support encryption for specific fields - look into the  pgcrypto module 


create table cryptosource (ID INT , avalue varchar(30));

insert into cryptosource (ID , avalue)
select 1 , 'bcbcbcbc'


SELECT avalue, crypt(avalue, gen_salt('md5')) AS hashed_value
FROM cryptosource;


'sha1' is an alternative option to 'md5'
