I know the key is correct because of the successful decryption using is something that I wrote this week as a way to securely embed a credential (e.g. I'm going to skip over my efforts in Python unless someone explicitly asks for them but instead hope for a solution using openssl. My efforts in Python were also unfruitful and lead to ValueError: Ciphertext length must be equal to key size. $ openssl enc -aes-128-cbc -iv $ivhex -kfile key.pem -nosalt -in edata.bin -out cdata.bin $ dd if=encrypted_assertion.bin of=edata.bin bs=16 skip=1ĥ184 bytes transferred in 0.002784 secs (1862219 bytes/sec) $ openssl rsautl -decrypt -in encrypted_assertion.bin -out plaintext -inkey key.pemĤ499476076:error:04FFF06C:rsa routines:CRYPTO_internal:data greater than mod len:/AppleInternal/BuildRoot/Library/Caches//Sources/libressl/libressl-47.100.4/libressl-2.8/crypto/rsa/rsa_eay.c:503:Īnd openssl enc to no avail (the content of cdata.bin is binary): $ dd if=encrypted_assertion.bin of=iv.bin bs=16 count=1ġ6 bytes transferred in 0.000436 secs (36692 bytes/sec) $ cat encrypted_assertion.txt | base64 -d > encrypted_assertion.bin MIIJQgIBADANBgkqhkiG9w0BAQEFAASCCSwwggkoAgEAAoICAQCoLiGwr/Y1vKPq So far I tried openssl rsautl: $ cat encrypted_assertion.txtĦMFicPXJ3ycJtj3grCsaY4zxk2eEXQ3s2eCXGDCtJMMKN4PcgCCihA/jljs2jbfo/bC+xegsU74u I checked with IT and they told me to figure out how to decrypt the EncryptedAssertion using the private key via openssl or a custom Python script.

I was able to decrypt a SAML response from a development stack I ran locally via but the page recommends not to upload production keys. Unfortunately the application logs the SAML response containing the EncryptedAssertion and I am unable to decrypt it locally. To provide further assistance to our customer we want to look at the Assertion in the SAML response to take a look at the problem's cause. We confirmed that our customer has configured NameID as outgoing claim in their ADFS: : NameID element must be present as part of the Subject in the Response message, please enable it in the IDP configuration Unfortunately our system complains about the SAML responses: Metadata has been exchanged and the connection works. Our customer uses ADFS as identity provider. Our system supports SAML2 and acts as service provider.
