shiro with jdbc and hashed passwords

Question

Here is my shiro config

[main]
authc.loginUrl = /site/index.jsp
authc.usernameParam = user
authc.passwordParam = pass
authc.rememberMeParam = remember
authc.successUrl = /site/home.jsp


jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.permissionsLookupEnabled=true
jdbcRealm.authenticationQuery = select password from users where username = ?
jdbcRealm.userRolesQuery = select role from users where username = ?

credentialsMatcher = org.apache.shiro.authc.credential.HashedCredentialsMatcher
credentialsMatcher.hashAlgorithmName = SHA-256
credentialsMatcher.storedCredentialsHexEncoded = true
credentialsMatcher.hashIterations = 5000
jdbcRealm.credentialsMatcher = $credentialsMatcher



jof = org.apache.shiro.jndi.JndiObjectFactory
jof.resourceName = jdbc/postgres
jof.requiredType = javax.sql.DataSource
jof.resourceRef = true
jdbcRealm.dataSource = $jof
securityManager.realms = jdbcRealm

[urls]
/theme/** = anon
/site/** = authc
/site/cards.jsp = roles[smoto,admin]
/site/jobs.jsp = roles[admin]

I created the hash like this for admin password admin

String hashedPassword = new Sha256Hash("admin", "",5000).toHex();

I inserted the hash into the db but my authentication fails every time, does anyone have any experience with this kind of setup with shiro? Also how would I enable debugging or logging for shiro?

EDIT: here is the correct set up for this kind of authentication, found it in another stackoverflow post

[main]
authc.loginUrl = /site/index.jsp
authc.usernameParam = user
authc.passwordParam = pass
authc.rememberMeParam = remember
authc.successUrl = /site/home.jsp

jdbcRealm=org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.permissionsLookupEnabled=false
jdbcRealm.authenticationQuery = select password from users where username = ?
jdbcRealm.userRolesQuery = select role from users where username = ?

ps = org.apache.shiro.authc.credential.DefaultPasswordService
pm = org.apache.shiro.authc.credential.PasswordMatcher
pm.passwordService = $ps

jof = org.apache.shiro.jndi.JndiObjectFactory
jof.resourceName = jdbc/postgres
jof.requiredType = javax.sql.DataSource
jof.resourceRef = true

jdbcRealm.dataSource = $jof
jdbcRealm.credentialsMatcher = $pm

#securityManager.realms = jdbcRealm

[urls]
/theme/** = anon
/site/** = authc
/site/cards.jsp = roles[smoto,admin]
/site/jobs.jsp = roles[admin]

The trick is to use the hashing tool that shiro provides and copy the exact output into database field "password", the whole string will contain info on what algorithm is used how many iteration etc, example:

$shiro1$SHA-256$500000$salthere$hashhere

Yes, the HashedCredentialsMatcher, while sufficient, is a bit older. You'll probably find Shiro's newer PasswordMatcher easier to use. You can configure its internal PasswordService pretty easily:

[main]
passwordService = org.apache.shiro.authc.credential.DefaultPasswordService
#configure the passwordService to use the settings you desire
#...
passwordMatcher = org.apache.shiro.authc.credential.PasswordMatcher
passwordMatcher.passwordService = $passwordService
#...
# Finally, set the matcher on a realm that requires password matching for account authentication:
myRealm = ...
myRealm.credentialsMatcher = $passwordMatcher

You can use an instance of the PasswordService in your application to create the password hash when you create an account or update the account's password:

String submittedPlaintextPassword = ...
String encryptedValue = passwordService.encryptPassword(submittedPlaintextPassword);
...
userAccount.setPassword(encryptedValue);
userAccount.save(); //create or update to your data store

Just make sure the passwordService configured in shiro.ini has the same configuration as the passwordService used in your application code.
