Hello,
I've seen in another forum that Quartus pro supports the RTL encrypted with Intel-FPGA-Quartus-RSA-1.
But I have the impression it is only supported by quartus prime and not quartus pro.
The problem is that I use a Stratrix 3 FPGA and cannot use any new version of quartus than 13.1.
Quartus pro 13.1 gives an error at the line 3 of reading the encrypted verilog code which is:
`pragma protect begin_protected
`pragma protect version=1
error:
Critical Warning (10191): Verilog HDL Compiler Directive warning at __defines.vh(2): text macro "pragma" is undefined
Error (10170): Verilog HDL syntax error at __defines.vh(3) near text "protect"; expecting ";"
Later on the file there are references for quartus (are they understood by quartus prime?):
`pragma protect key_keyowner="Intel Corporation"
`pragma protect key_keyname="Intel-FPGA-Quartus-RSA-1"
`pragma protect key_method="rsa"
`pragma protect encoding = (enctype = "base64", line_length = 76, bytes = 256 )
`pragma protect key_block
n0UPGPFspR1ysbje0ATJO017usMhu6rHITQH+dT3Twom+D...
I was planning to use Synplify to create the gate netlist but the output is encrypted in the vqm,
which also gives error with quartus.
Alex.

Apparently the support was introduced at Quartus Pro 17.1,
can you confirm?

Yes, you are right.
IEEE 1735 Encryption Standard is only supported in Quartus Prime Pro Edition. Quartus Standard/Lite does not support it unfortunately.
