I need to create structure with ripemd160 digest and ripemd160WithRSA signature. I can set digest algorithm to CMSSignedDataGenerator but generated signed data structure end with: 672:d=5 hl=2 l= 13 cons: SEQUENCE 674:d=6 hl=2 l= 9 prim: OBJECT :rsaEncryption 685:d=6 hl=2 l= 0 prim: NULL 687:d=5 hl=3 l= 128 prim: OCTET STRING [HEX DUMP]:... and I need it to look like this: 676:d=5 hl=2 l= 10 cons: SEQUENCE 678:d=6 hl=2 l= 6 prim: OBJECT :ripemd160WithRSA 686:d=6 hl=2 l= 0 prim: NULL 688:d=5 hl=3 l= 128 prim: OCTET STRING [HEX DUMP]:... I'm not expert in this field, but I know, that signature is in fact just encrypted digest. And as my digest is correctly generated using ripemd160 I think, that the signature is generated correctly and only thing I need to do is to replace "rsaEncryption" with "ripemd160WithRSA". Can anybody confirm this ? Or am I wrong ? If so, how can I generate correct signature.
