Так работает

const imageInput = document.getElementById('imageInput');
    const encryptedTextDiv = document.getElementById('encryptedText');
    const decryptionKeyInput = document.getElementById('decryptionKey');
    const decryptButton = document.getElementById('decryptButton');
    const decryptedImageDiv = document.getElementById('decryptedImage');

    imageInput.addEventListener('change', (event) => {
      const selectedImage = event.target.files[0];
      const key = "123456";

      const reader = new FileReader();
      reader.onload = function(event) {
        const encryptedImage = CryptoJS.AES.encrypt(event.target.result, key).toString();
        localStorage.setItem('encryptedImage', encryptedImage);

        encryptedTextDiv.textContent = encryptedImage.toString();
      };
      reader.readAsDataURL(selectedImage);
    });

    decryptButton.addEventListener('click', () => {
      const decryptionKey = decryptionKeyInput.value;
      const encryptedImage = localStorage.getItem('encryptedImage');

      const decryptedBytes = CryptoJS.AES.decrypt(encryptedImage, decryptionKey).toString(CryptoJS.enc.Utf8);
     // const decryptedImageBlob = new Blob([decryptedBytes], { type: 'image/jpeg' });

     // const decryptedImageURL = URL.createObjectURL(decryptedImageBlob);
     const img = document.createElement('img');
      img.src = decryptedBytes;

      decryptedImageDiv.innerHTML = '';
      decryptedImageDiv.appendChild(img);
    });
