Kas ir teksta atšifrēšana?

Teksta atšifrēšana ir process, kurā šifrēts teksts (šifra teksts) tiek pārveidots atpakaļ sākotnējā lasāmā formātā (vienkāršā tekstā). Tam ir nepieciešama pareizā atšifrēšanas atslēga un algoritms.

Supported Algorithms:

Symmetric Decryption (AES):

• AES-GCM (Recommended): Provides authenticated encryption with associated data (AEAD). Most secure for general use.
• AES-CBC: Traditional block cipher mode. Requires padding.
• AES-CTR: Counter mode. Converts block cipher to stream cipher.

Asymmetric Decryption (RSA):

• RSA-OAEP: Uses private key for decryption. Requires the corresponding private key to the public key used for encryption.

Expected Input Format:

For AES algorithms: JSON with base64-encoded components

{"iv": "base64_encoded_iv", "data": "base64_encoded_ciphertext"}

Also supports legacy hex format:

{"iv": "hex_encoded_iv", "data": "hex_encoded_ciphertext"}

For RSA: Base64-encoded ciphertext only

base64_encoded_ciphertext

Kā izmantot

1. Ielīmējiet šifrēto tekstu.

2. Ievadiet paroli, kas tika izmantota šifrēšanai.

3. Noklikšķiniet uz "Atšifrēt".

4. Skatiet sākotnējo tekstu.

5. The decrypted text is automatically displayed as you type.

6. Copy the decrypted result for use in your application.

Additional Tips:

• For AES: Use the same secret key that was used for encryption
• For RSA: You need the private key corresponding to the public key used for encryption
• Automatic format detection: The tool automatically detects base64 or hex encoding
• Error handling: If decryption fails, check that you're using the correct algorithm and key

Security Notes

This tool uses the browser's native Web Crypto API for secure decryption. All decryption happens locally in your browser - no data or keys are ever sent to external servers. Make sure you're using the correct algorithm and key that match the encryption method used. The tool supports both base64 (standard) and hex (legacy) encoding formats for AES encrypted data.

Important Notes:

• All decryption happens locally in your browser using the Web Crypto API
• Your private keys and secrets never leave your browser
• For RSA decryption, you decrypt with a private key; the data was encrypted with the corresponding public key
• Keep your private keys and secret keys secure - they are the only way to decrypt your data
• The tool supports both base64 (standard) and hex (legacy) encoding formats
