• Output:
  • None

Examples

Using an absolute path

from desilofhe import Engine

engine = Engine(use_multiparty=True)
secret_key_1 = engine.create_secret_key()
secret_key_2 = engine.create_secret_key()
public_key_a = engine.create_public_key_a()
public_key_b1 = engine.create_public_key_b(secret_key1, public_key_a)
public_key_b2 = engine.create_public_key_b(secret_key2, public_key_a)
public_key = engine.create_multiparty_public_key([public_key_b1, public_key_b2], public_key_a)

message = [1, 2, 3]
ciphertext = engine.encrypt(message, public_key)
decrypted_share = engine.individual_decrypt(ciphertext, secret_key_1)
engine.write(decrypted_share, "/opt/desilo/decrypted_share")

Using a relative path

from desilofhe import Engine

engine = Engine(use_multiparty=True)
secret_key_1 = engine.create_secret_key()
secret_key_2 = engine.create_secret_key()
public_key_a = engine.create_public_key_a()
public_key_b1 = engine.create_public_key_b(secret_key1, public_key_a)
public_key_b2 = engine.create_public_key_b(secret_key2, public_key_a)
public_key = engine.create_multiparty_public_key([public_key_b1, public_key_b2], public_key_a)

message = [1, 2, 3]
ciphertext = engine.encrypt(message, public_key)
decrypted_share = engine.individual_decrypt(ciphertext, secret_key_1)
engine.write(decrypted_share, "decrypted_share")
