[Trustedjava-support] Failed to get RSA Exponent using getAttribData

[ravi k. <rk...@ya...>]

Hi 
 
I recently started working on jTss. 
I have created a 2048 bit legacy key.
 
I am getting Internal Software error while trying to export rsa key info using the below method
 
objKey.getAttribData(TcTssConstants.TSS_TSPATTRIB_RSAKEY_INFO, TcTssConstants.TSS_TSPATTRIB_KEYINFO_RSA_EXPONENT);
 
The complete error stack is given below
 
iaik.tc.tss.api.exceptions.tsp.TcTspException: 
TSS Error:
error layer:                0x3000 (TSP)
error code (without layer): 0x04
error code (full):          0x3004
error message: An internal SW error has been detected.
additional info: Getter method did throw unknown exception (not a TcTssException).
null
            at iaik.tc.tss.impl.java.tsp.TcAttributes.getAttribData(TcAttributes.java:170).
 
 
 
but when i try to get rsa modulus using below method call
 
 
objKey.getAttribData(TcTssConstants.TSS_TSPATTRIB_RSAKEY_INFO, TcTssConstants.TSS_TSPATTRIB_KEYINFO_RSA_MODULUS);
 
i am getting result without error.
 
My system configuration is windows7 Ultimate 64 bit,java-64 bit
 
 
Kindly assist me
 
 
Regards
Ravi
