> The {{org.apache.shiro.realm.jdbc.JdbcRealm}} class, when configured with SaltStyle.COLUMN, assumes that password column is Base64 but salt column is utf8 bytes.
> The password is returned as a {{char[]}} (see JdbcRealm.java:241), which {{org.apache.shiro.authc.credential.HashedCredentialsMatcher}} (see HashedCredentialsMatcher.java:353):
> {code}
>         if (credentials instanceof String || credentials instanceof char[]) {
>             //account.credentials were a char[] or String, so
>             //we need to do text decoding first:
>             if (isStoredCredentialsHexEncoded()) {
>                 storedBytes = Hex.decode(storedBytes);
>             } else {
>                 storedBytes = Base64.decode(storedBytes);
>             }
>         }
> {code}
> However, the salt is returned as a {{ByteSource}}, by converting the DB-returned String into its UTF-8 bytes. See JdbcRealm.java:224:
> {code}
>             if (salt != null) {
>                 info.setCredentialsSalt(ByteSource.Util.bytes(salt));
>             }
> {code}
> This is broken and inconsistent.
> Not all salt byte[]s are valid UTF8 strings, so the default assumption should be that the salt column is Base64 encoded.
