Hva er tekst-dekryptering?

Tekst-dekryptering konverterer kryptert tekst tilbake til den opprinnelige lesbare teksten. Du trenger samme passord som ble brukt for kryptering. Dette verktøyet bruker AES-256-GCM for dekryptering, all behandling skjer i din nettleser.

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

Hvordan bruke

1. Lim inn kryptert tekst.

2. Skriv inn passordet som ble brukt for kryptering.

3. Klikk på "Dekrypter".

4. Se den opprinnelige teksten.

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

Sikkerhetsmerknader

Dette verktøyet bruker nettleserens innebygde Web Crypto API for sikker dekryptering. All dekryptering skjer lokalt i nettleseren din - ingen data eller nøkler sendes noensinne til eksterne servere. Sørg for at du bruker riktig algoritme og nøkkel som matcher krypteringsmetoden som ble brukt. Verktøyet støtter både base64 (standard) og hex (eldre) kodingsformater for AES-krypterte 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

Dekrypter AES-256-GCM kryptert tekst direkte i nettleseren. Ingen data sendes til servere.
