Hello,

Is there currently any known issue with the CSE's MP Compression function?  My chip is disagreeing with an offline Python script on all these calculations.  Everything else seems to work fine.

Plaintext:

0x12341234_12341234_12341234_12341234

CSE Inputs:

P1 = 256 (stored as 64 bit number)

P2 = Pointer to plaintext

P3 = Pointer to result array

Output from Python script:

0xe107cc79_b2c397f7_bb5ccdfe_ded2e0b7

Output from CSE:

0xba194b65_128e8774_9f69c446a_3f2e1fb1

Thanks!
