AES in CTR mode

Question

I’m developing AES in CTR mode for my work, but I’m not getting it to return the right result, both at Encrypt and at Decrypt,.

Follow the code:

class AESCipher(object):
    def __init__(self, key):

       

    def encrypt(self, plain_text):
        print("Plaint_text com pad: ",plain_text)
        bytes = PBKDF2(plain_text.encode("utf-8"), "salt".encode("utf-8"), 48, 128)
        iv = bytes[0:16]
        self.key = bytes[16:48]
        print("key: ", self.key)
        #iv = int(self.block_size)
        print("iv:", iv)
        #iv_int = int(hex(iv), 16)
        iv_int = int.from_bytes(iv, "little")
        #print("iv_int:", iv_int)
        ctr = Counter.new(AES.block_size*8, initial_value=iv_int)
        print("ctr:", ctr)
        cipher = AES.new(self.key, AES.MODE_CTR, counter=ctr)
        print("cipher:", cipher)
        encrypted_text = cipher.encrypt(plain_text.encode())
        print("encrypted_text:", encrypted_text)
        aux = b16encode(encrypted_text).decode("utf-8")
        return (aux)

    def decrypt(self, encrypted_text):
        encrypted_text = b16decode(encrypted_text)
        bytes = PBKDF2(str(encrypted_text).encode("utf-8"), "salt".encode("utf-8"), 48, 128)
        iv = bytes[0:16]
        #iv = encrypted_text[:self.block_size]
        #print(hex(iv))
        #iv_int = int(str(iv).encode('hex'), 16)
        iv_int = int.from_bytes(iv, "little")
        ctr = Counter.new(128, initial_value=iv_int)
        cipher = AES.new(self.key, AES.MODE_CTR, counter=ctr)
        plain_text = cipher.decrypt(encrypted_text[self.block_size:])
        result = b16encode(plain_text).decode("utf-8")
        return result

Entrances:

obj = Aescipher("000102030405060708090A0B0C0D0E0F")

aux = obj.Encrypt("00112233445566778899ABBCCDEEFF")

Decrypted text does not match clear text. Neither does encrypted text. this was to be the result of Encrypt: 69C4E0D86A7B0430D8CDB78070B4C55A
