1. Method for generating address and private key Back Dir

1.1 Generate address and private key process

• Execute in the compilation directory, get cmdWallet execution file

cd cpp-lsac/build : Enter the directory
cmake ..          : Execute instruction
make              : Execute instruction
cd cpp-lsac/build/wallet/cmdWallet : 此目录下可找到刚才编译好的cmdWallet执行文件

• run

 ./wallet/cmdWallet/cmdWallet -g 1

• The program will randomly generate a private key and address

private-key: wDnHJb3kRV7YnUojQ6sjYnfbe93vK1YVCHHPV71GAcA
address    : a49c22485d140e7c725a9d40ce801d19dbb88784
public-key : cd4846e7f5ab2d29e85e033f89cb7000a49bd223ca9fd5df5ef7c162740a7cb1336006807d5e2b8d1c6760922e7399e8ffd3261a16f4c33dd81a41a31822600f

• Remarks: The API calls the KeyPair :: create () interface, and then obtains a random number by calling std :: random_device, and generates a public and private key pair, which is only allowed for Linux before; under a specific version of a specific platform, the random number entropy obtained by std :: random_device If the value is insufficient, the private key is in danger of being predicted.

• The method of generating the address and private key in the above process is for reference only, and can be generated by yourself.

• Separate private key generation method

1.2 base58 convert private key formatOne Back Dir

• run

./cmdWallet --pri-tf wDnHJb3kRV7YnUojQ6sjYnfbe93vK1YVCHHPV71GAcA

• Return result

address : a49c22485d140e7c725a9d40ce801d19dbb88784
pri-base58 : wDnHJb3kRV7YnUojQ6sjYnfbe93vK1YVCHHPV71GAcA
pri-big int : 0de3d09c2ee9e4c34e47a68edea0ebec6386e9477e6b5c389ff5bfbe8dd34a53
public address : cd4846e7f5ab2d29e85e033f89cb7000a49bd223ca9fd5df5ef7c162740a7cb1336006807d5e2b8d1c6760922e7399e8ffd3261a16f4c33dd81a41a31822600f

From the returned results, we can see: pri-big int: 0de3d09c2ee9e4c34e47a68edea0ebec6386e9477e6b5c389ff5bfbe8dd34a53 is the private key conversion format we need to get

1.3 base58 convert private key formatTwo Back Dir

• Command
  • Note: At this time, you need to add 0x, such as: 0x0de3d09c2ee9e4c34e47a68edea0ebec6386e9477e6b5c389ff5bfbe8dd34a53

./cmdWallet --pri-tf 0x0de3d09c2ee9e4c34e47a68edea0ebec6386e9477e6b5c389ff5bfbe8dd34a53

• Return result

address : a49c22485d140e7c725a9d40ce801d19dbb88784
pri-base58 : wDnHJb3kRV7YnUojQ6sjYnfbe93vK1YVCHHPV71GAcA
pri-big int : 0de3d09c2ee9e4c34e47a68edea0ebec6386e9477e6b5c389ff5bfbe8dd34a53
public address : cd4846e7f5ab2d29e85e033f89cb7000a49bd223ca9fd5df5ef7c162740a7cb1336006807d5e2b8d1c6760922e7399e8ffd3261a16f4c33dd81a41a31822600f

It can be seen from the returned result: pri-base58: wDnHJb3kRV7YnUojQ6sjYnfbe93vK1YVCHHPV71GAcA is the format after conversion of the private key we need
