Chilkat2-Python

secp256k1 Key Generation and Keccak-256

See more ECC Examples

Starting in v11.0.0, Chilkat supports both secp256k1 key generation and Keccak-256 directly. These algorithms are typically used for Bitcoin and Ethereum. Chilkat2-Python

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Create a Fortuna PRNG and seed it with system entropy.
# This will be our source of random data for generating the ECDSA private key.
fortuna = chilkat2.Prng()
entropy = fortuna.GetEntropy(32,"base64")
success = fortuna.AddEntropy(entropy,"base64")

ecc = chilkat2.Ecc()

# Generate a random ECDSA private key on the secp256k1 curve.
privKey = chilkat2.PrivateKey()

if (success == False):
    print(ecc.LastErrorText)

# Show how to compute the Keccak-256 hash in a few ways.
sb = chilkat2.StringBuilder()
sb.Append("hello")

print("keccak-256: " + sb.GetHash("keccak-256","hex_lower","utf-8"))

# Output:
# keccak-256: 1c8aff950685c2ed4bc3174f3472287b56d9517b9c948127319a09a7a36deac8

# To keccak-256 hash binary data
bd = chilkat2.BinData()
bd.AppendEncoded("00010203040506","hex")

# Output:
