Description

Primo Authentication has been configured to use ADFS (introduced in Primo August 2016 Release), but receives the following Exception:

Error decrypting the encrypted data element
org.apache.xml.security.encryption.XMLEncryptionException: Illegal key size
Original Exception was java.security.InvalidKeyException: Illegal key size
at org.apache.xml.security.encryption.XMLCipher.decryptToByteArray(XMLCipher.java:1822)
at org.opensaml.xml.encryption.Decrypter.decryptDataToDOM(Decrypter.java:596)
at org.opensaml.xml.encryption.Decrypter.decryptUsingResolvedEncryptedKey(Decrypter.java:795)

[...etc]

Resolution

Primo may be missing Java Cryptography Extension (JCE) Unlimited Strength JAR installed in your Primo environment required for ADFS support.

This third-party JAR is included in all Primo environments hosted by Ex Libris, but is not included in Primo build available for Local Primo installations.

Please contact Ex Libris Support if you have a Local Primo installation and need this JAR.
