# Use Crypto Utilities

You can work with the Private Key, Public Key, and Address methods.

# Private Key

You can create a private key from:

Seed phrase.
Seed bytes.
Randomly generated seed bytes.
Bytes.
Encoded string.

# Create Private Key from Seed Phrase

# Necessary import.
import pywaves as pw

# Specify your account's seed phrase.
seed_phrase = "PASTE YOUR SEED PHRASE"

# Creation of the private key from the seed phrase.
address = pw.Address(seed=seed_phrase)
privateKey = address.privateKey

# Print the output.
print("Sender's Private Key:", privateKey)

# Create Private Key from Seed Bytes

# Necessary imports.
import pywaves as pw
import base58

# Creation of a byte array.
seed_bytes = bytes([1, 2, 3, 4, 5, 6, 7]) # Byte array example.

# Encoding bytes to a Base58 string to use as a seed.
seed_phrase = base58.b58encode(seed_bytes).decode()

# Creation of the private key from the seed bytes.
address = pw.Address(seed=seed_phrase)
privateKey = address.privateKey

# Print the output.
print("Sender's Private Key:", privateKey)

# Create Private Key from Randomly Generated Seed Bytes

# Necessary imports.
import pywaves as pw
import os
import base58

# Generation of random seed bytes.
random_seed_bytes = os.urandom(32)

# Encoding to Base58 to use as a seed.
seed_phrase = base58.b58encode(random_seed_bytes).decode()

# Creation of the private key from the randomly generated seed bytes.
address = pw.Address(seed=seed_phrase)
privateKey = address.privateKey

# Print the output.
print("Sender's Private Key:", privateKey)

# Create Private Key from Bytes

# Necessary imports.
import pywaves as pw
import base58

# Creation of a byte array.
bytes_array = bytes([56, 253, 37, 64, 2, 38, 78, 37, 158, 211, 233, 117, 14, 88, 20, 42,
247, 21, 55, 87, 117, 248, 175, 77, 77, 157, 169, 233, 7, 116, 157, 236]) # Bytes example.

# Encoding bytes to Base58 string to use as a seed.
seed_phrase = base58.b58encode(bytes_array).decode()

# Creation of the private key from the bytes.
address = pw.Address(seed=seed_phrase)
privateKey = address.privateKey

# Print the output.
print("Sender's Private Key:", privateKey)

# Create Private Key from an Encoded String

# Necessary import.
import pywaves as pw

# Creation of a Base58 string.
base58_string = "A5u9Ugt2nG1rWfLkL7pzZrtkP8LgF2rD3g1XBjsF8ZzV" # Base58 string example.

# Creation of the private key from the Base58 string seed.
address = pw.Address(seed=seed_phrase)
privateKey = address.privateKey

# Print the output.
print("Sender's Private Key:", privateKey)

# Public Key

You can create a public key from an address. Place the following code after the address generation:

# Creation of the public key.
publicKey = address.publicKey 

# Print the output.
print("Sender's Public Key:", address.publicKey)

# Address

You can create an address from the private key. Place the following code after the private key generation:

# Set the node link and chain ID.
pw.setNode(
	# Specify the link for the network:
	# - Mainnet: 'https://nodes.wavesnodes.com/'
	# - Testnet: 'https://nodes-testnet.wavesnodes.com/'
	# - Stagenet: 'https://nodes-stagenet.wavesnodes.com/'
	node='https://nodes-testnet.wavesnodes.com', 

	# Specify the network chain ID:
	# - Mainnet: 'M'
	# - Testnet: 'T'
	# - Stagenet: 'S'
	chain='T'
)

# Print the output.
print("Sender's Address:", address)
