6. User generates epoch key and epoch key proof

npx ts-node cli/index.ts genEpochKeyAndProof \
    -x $UNIREP_CONTRACT_ADDRESS  \
    -id $USER_IDENTITY  \
    -n 0

info

NOTE: -id is user's identity and -n is epoch key nonce which should be less than the system parameter maxEpochKeyNonce

See: cli/genEpochKeyAndProof for more genEpochKeyAndProof options.

NOTE: epoch key and base64url encoded epoch key proof and public signals will be printed and they should be handed to attester to be verified, for example:

Epoch key of epoch 1 and nonce 0: 1916576171
