kandi X-RAY | Cryptosuite Summary
cryptosuite is a cryptographic library for arduino (including sha and hmac-sha). it currently supports secure hashing and hashed message authentication using sha-1, sha-256, hmac-sha-1 and hmac-sha-256. installation: make a 'libraries' directory with your arduino sketches folder if you do not already have one. copy the 'sha' directory into that directory. restart arduino to rescan for new libraries. using sha-1: #include "sha1.h" ... uint8_t *hash; sha1.init(); sha1.print("this is a message to hash"); hash = sha1.result();. the hash result is then stored in hash[0], hash[1] .. hash[19]. using hmac-sha-1: #include "sha1.h" ... uint8_t *hash; sha1.inithmac("hash key",8); // key, and length of key in bytes sha1.print("this is a message to

QUESTION
I am trying to sign transaction proposals with offline key. I have generated signed certificate by Org CA
and now I am trying to create User
with fabric-common
nodejs SDK version 2.2.5.
ANSWER
Answered 2021-Mar-17 at 11:45So the problem was that I was using node v12.6.0
which is required by fabric-common
module. When I downgraded node version to v11.6.0
and installed dependencies with flag --ignore-engines
everything worked as expected.
QUESTION
I have been trying out to invoke and querying transactions from the Java SDK for the BYFN network in Hyperledger Fabric v1.4.4 So far i have started the network (which has two peers in two orgs, an orderer and chaincode mycc installed). The network starts successfully, and scripts and tests complete (As per the end of execution the values of a and b after the byfn.sh scripts runs is 90 and 210 respectively)
Now I have my Java SDK, through which the query proposal response works correctly (returns 90 and 210), but after moving (doing the invoke) request and then querying the value returned is still 90, there is no change, I am not sure what I am doing wrong here.
My code:
