在postgres中加密密码转换

Question

I am converting oracle stored passwords to postgres. We stored password in oracle as follows.

ltrim( to_char( dbms_utility.get_hash_value( upper(name)||'/'||upper(password), 05736, power(2,20) ),rpad( 'X',43,'X')||'X' ) ) 

if i write name and password as ' jhon ' it returns hash value ' 42B21 '. I need alternative for the same kind of functionality in postgres. Appreciate your help!

Answer 1

If password_encryption is md5 , you can calculate the encoded password as

'md5' || md5(password || username)

With scram-sha-256 , it is much more complicated.
