IJ08530: IBMPKCS11IMPL PROVIDER USES THE WRONG RSA CIPHER MECHANISM FOR THE RSA/ECB/PKCS1PADDING CIPHER

APAR status

• Closed as program error.

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

Local fix

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.
