Migrate users from Asp.net Identity to Auth0

[Uday81]

Hi, I’m trying to move an user from Asp.net Identity to Auth0 using the Import extension Auth0 provided.

Asp.net Identity saves the hash and security stamp in AspnetUsers table.

Here is a sample:

Hash: AQAAAAEAACcQAAAAEHdxpBZPL+ZGQ++wgRm3GGiiWjlB+dLr0le6qgnMsNpGZ3qLzI5AoSpcpgrwTtUaUg==

Salt: RGSLRDKJ5OTVS4I6SW7BT5TOW5BCHXOO

Original password for testing: Password@1

I tried the following json to import an user with the above password.

[
	{
		"user_id": "e5324e2e-4f67-474d-a65a-be689aecc011",
		"email": "MigrationTest@test.com",
		"custom_password_hash": {
			"algorithm": "sha1",
			"hash": {
				"value": "AQAAAAEAACcQAAAAEHdxpBZPL+ZGQ++wgRm3GGiiWjlB+dLr0le6qgnMsNpGZ3qLzI5AoSpcpgrwTtUaUg==",
				"encoding": "utf8"
			},
			"salt": {
				"value": "UkdTTFJES0o1T1RWUzRJNlNXN0JUNVRPVzVCQ0hYT08="
			}
		},
		"given_name": "Test1",
		"family_name": "Test2",
		"nickname": "Tes3",
		"blocked": false,
		"email_verified": true
	}
]

I was able to import the user successfully but when I try to login with the credentials, Auth0 not able to validate the password. “Verification failed for the provided custom_password_hash”
I tried to replace with md5, sha1, sha256 with different positions prefix and suffix. No success.

Any help is greatly appreciated. This is a critical step in our migration now.

Hi @Uday81,

It looks like it might be the encoding.

The doc says

When the algorithm is set to md4 , md5 , sha1 , sha256 , or sha512 :

• hash.encoding must be either hex or base64 .

Sure Thanks. Let me give a try.
