* Convert private key to wallet import format (WIF)

* 1 - Take a private key

*
* 2 - Add a 0x80 byte in front of it for mainnet addresses or 0xef for testnet addresses.Also add a 0x01 byte at the end if the private key will correspond to a compressed public key
* 800C28FCA386C7A227600B2FE50B7C_SAMPLE_PRIVATE_KEY_DO_NOT_IMPORT_AE11EC86D3BF1FBE471BE89827E19D72AA1D
*
* 3 - Perform SHA-256 hash on the extended key

*
* 5 - Take the first 4 bytes of the second SHA-256 hash, this is the checksum

*
* 7 - Convert the result from a byte string into a base58 string using Base58Check encoding.This is the Wallet Import Format
