Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    The customer experienced a "No such algorithm" exception while
    attempting to get an RSA/ECB/PKCS1Padding cipher instance.  An
    IBM Crypto Express adapter configured in CCA mode was being
    used.
    java.security.NoSuchAlgorithmException: No such algorithm:
    RSA/ECB/PKCS1Padding

Problem summary

  • The customer experienced a "No such algorithm" exception while
    using an IBM Crypto Express adapter configured in CCA mode.
    java.security.NoSuchAlgorithmException: No such algorithm:
    RSA/ECB/PKCS1Padding
            at javax.crypto.Cipher.getInstance(Unknown Source)
            at test.decryptMessage(test.java:388)
            at test.runTest(test.java:164)
            at test.runTest(test.java:136)
            at test.main(test.java:110)
    This exception was seen because the IBMPKCS11Impl provider was
    using the CKM_RSA_X_509 mechanism for the RSA/ECB/PKCS1Padding
    cipher.  Not only is CKM_RSA_X_509 the incorrect mechanism for
    this cipher, CKM_RSA_X_509 is not available on an IBM Crypto
    Express adapter configured in CCA mode.  The IBMPKCS11Impl
    provider should have been using the CKM_RSA_PKCS mechanism
    instead.
    

Problem conclusion

  • The IBMPKCS11Impl provider has been modified to use the
    CKM_RSA_PKCS mechanism for the RSA/ECB/PKCS1Padding cipher.
    The associated CMVC defect is 117903.
    The associated RTC problem report is 138957.
