qcrypt:test.rbf:8068: unexpected end-of-file

[Steve-Mowbray-ENL]

Hi 

When running Qcrypt on my working RBF configuration file I get the following result:

C:\Users\steve>D:/intelFPGA/21.1/quartus/bin64/qcrypt --encrypt --keyfile=keyfile.key --keyname=key1 --keystore=otp test.rbf test_qcrypt.rbf

qcrypt:test.rbf:8068: unexpected end-of-file

Any clues as to what could be wrong would be appreciated - I am confused as the unencrypted  RBF file works fine with passive serial configuration..

Thanks 

Steve

Sorted -- according to AN-556:

"Encryption and compression cannot be used simultaneously in 20 nm FPGAs."

Assignments->Settings->"Device and Pin Options..."->Configuration->"Generate compressed bitstreams" seems to be checked by default -- unchecked and the rebuilt RBF gets encrypted correctly by "Qcrypt" tool (at double the size...).
