bad padding exception when attempting to decrypt token

This is actually a common issue when users are encrypting in one language and decrypting in another. If you enabled IncludeExceptionDetailInFaults in the STS web.config like mentioned above, it should give you a decent error to research and fix, like the one detailed in the section below. Note: The maximo.properties file should be automatically re-encrypted following the completion of the upgrade. thats why I was using Buffer.BlockCopy. In The application requested an ID token from the authorization endpoint, but did not have ID token implicit grant enabled. If the token changes only slightly, I may be able to use the data to figure out the public key. You can do that by running this PowerShell script: This script will get each web application in the farm, and then contact the STS to issue a new security token within the context of that web app.When successful, it should produce output like this: Web Application Context: https://teams.contoso.com/Token: SamlAssertionKeyIdentifierClause(AssertionId = ‘_d47eb32c-4ff5-4b6c-86e1-12c18c9be8fa’)**************************Web Application Context: http://mysite.contoso.com/Token: SamlAssertionKeyIdentifierClause(AssertionId = ‘_78bc4df4-062f-45ed-978f-0fc646ffccda’)**************************Web Application Context: http://ourweb.contoso.com/Token: SamlAssertionKeyIdentifierClause(AssertionId = ‘_a7e31b81-0ec5-4bc1-9ef0-f757647a74c5’)**************************. There are two errors that are NOT the usual "bad decrypt" one - one is "ACCESS DENIED" - our original - and the other is "Bad signature!". It’s called “The Security Token Service is not available”. I could create my own packet with the previously recorded token and signature, which you may not Right click on securitytoken.svc and choose Browse.

Ok, so the problem is in padding. I am trying to decrypt an encrypted value sent back form a pinpad. Some how, I am suspecting there is something wrong with the base64 conversion, but I can;t really tell what's wrong with it. This sounds an awful lot like a padding oracle vulnerability! Join our community of data professionals to learn, connect, share and innovate together "dv" is encrypted as -7f16992f0aa153. In cryptography, the one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is no smaller than the message being sent. That scheme is known as RSA-PKCS#1v1.5, and it was famously broken by Daniel Bleichenbacher in the late 1990s. For the token decrypting certificate, confirm the expiration date is 1 year from the current date. 7. Required for decrypt(). Cipher.getInstance("RSA"); uses platform defaults, a frequent source of bugs. The Padding Oracle Attack. In SharePoint, the STS is used to generate security tokens for claims-based authentication purposes. Determining the Token Construct _ The only variable blocks are the last two (possibly a "last accessed" timestamp or similar timeout mechanism) _ Register another account with a username of 'c' x 32, the maximum length permitted, and observe the value of the EE cookie Instead, you can use the following PowerShell to add a DLL to the GAC: After adding the custom DLL to the GAC, you’ll want to reset IIS or recycle the application pool for the STS to make sure it gets loaded.

This book is a valuable resource for security officers, administrators, and architects who want to understand and implement enterprise security following architectural guidelines. Then create your RSACryptoServiceProvider object. Save it in a clientSignature variable, which is an array of bytes. The Padding Oracle Attack. The sign/verify calls are (for a moment, insignificant) The data is key during this step. Using 1024 when decrypting in Scenario 2 gives a fail, but when using 1032 in Scenario 2 it success decrypting the file (Remember Scenario 1 buffer is 1032 but throws a "BadPaddingException: Pad block corrupted" cause the key is sent encrypted and later decrypted): Encryption: Fixed issue with null exception introduced in last release when trying to run Ad Detect task on already decrypted file. A zero value means false, and a nonzero value means true. The comment Sha1withRSA is a bit misleading, since it is SHA256, you may want to change that. In terms of Java support on the server, it doesn't matter how you come up with the end-buffer, just make sure that the buffers' data are the same when you try to work with them. Verify that you have a 128 byte token and 128 byte signature (because you don't). By default node uses PKCS padding, but Python uses null-byte padding instead. *. To decrypt the encryptedData you need to have the apikey and shared secret for the application (appID) you are using. You need to specify the proxy parameters as shown in the following examples: HttpHost proxy = new HttpHost ("proxy.test.com", 8080, "http"); RequestConfig config = RequestConfig.custom ().setProxy (proxy).build (); Cryptopals: Exploiting CBC Padding Oracles.
