Re: User password encryption using a stronger hashing function?

No one has responded to my questions. I am wondering if anyone can point me to where in postgresql source code I can further look into the issue and explore the possibility of this change?  Thanks.

By default, postgresql encrypts user passwords using the MD5 hashing function. They can be seen as "md5....." in the rolpassword column of the pg_authid table. Is there a mechanism that allows us to change this default behavior such that postgresql can encrypt the passwords stored in the pg_authid table using a stronger hashing function such as SHA1?

Postgresql conf file has a property "ssl_ciphers" in which you can specify a list of ciphers. But they are only used on ssl connections and have no impact on the ciphers used in user password encryption. Is this correct?
