decrypt_to_plaintext

GLEngine.decrypt_to_plaintext(ciphertext)

Decrypts a ciphertext without decoding it. A plaintext is returned.

• Input:
  • GLCiphertext
• Output:
  • GLPlaintext

import numpy as np

from desilofhe import GLEngine

engine = GLEngine()
secret_key = engine.create_secret_key()

message = np.ones(engine.shape)
ciphertext = engine.encrypt(message, secret_key)
decrypted = engine.decrypt_to_plaintext(encrypted, secret_key)
decoded = engine.decode(decrypted)

While it has little practical use, this function can be used when you want to replicate the API behavior of traditional homomorphic encryption libraries, such as SEAL, on a 1:1 basis.
