Python AES_SIV Exemples

Exemple #1

def test():
    aead = aes_siv.AES_SIV()

    print("Key:  ", hexlify(key), "(%d bytes)" % len(key))
    print("AD:   ", hexlify(ad), "(%d bytes)" % len(ad))
    print("Nonce:", hexlify(nonce), "(%d bytes)" % len(nonce))
    print("Plain:", hexlify(plaintext), "(%d bytes)" % len(plaintext))
    print()

    ciphertext = aead.encrypt(key, nonce, plaintext, ad)

    print()
    print("Out:   ", hexlify(ciphertext), "(%d bytes)" % len(ciphertext))
    print()

Exemple #2

 def get_aead(self):
     if self.aead is None:
         self.aead = aes_siv.AES_SIV()
     return self.aead

Exemple #3
