Recently i have made my custom board with BF547 and i couldn't to find a solution to secure my codes.

Fortunately i found perfect "signtool" and i could work with it successfully .the question is:

1- Does "signtool" support SHA-1 because BF547 only knows SHA-1 Decryption algorythm.If yes how can i tell signtool to make my file with SHA-1.I think it only supports 224-bit Elliptic Curve Digital Signature and 256.these are not SHA-1 algorithms

If "NO" please guide me how can i do it.

2- should i program just the output file of signtool in my external flash and then program my public key in OTP? is there any tasks that i must do?

 

Thank you in advance
