A dekrüpteerimisvahend (decryption tool) is a piece of software or hardware designed to reverse the process of encryption, making encrypted data readable again. Encryption is the process of encoding information so that only authorized parties can access it. Decryption is the reverse, using a specific key or algorithm to unscramble the data.

These tools are crucial for various applications, including cybersecurity, digital forensics, and espionage. In cybersecurity, decryption tools are used by security professionals to analyze malware, recover lost data, or investigate security breaches. For instance, if a system has been encrypted by ransomware, a decryption tool might be used to restore the files if a valid decryption key is available.

Digital forensics often relies on decryption tools to access evidence stored on encrypted devices or in encrypted files. Law enforcement agencies and forensic investigators use these tools to unlock crucial information during investigations.

However, decryption tools also have potential for misuse. Malicious actors can employ them to decrypt stolen sensitive information or to bypass security measures. The effectiveness of a decryption tool is entirely dependent on the strength of the original encryption algorithm and the availability of the correct decryption key. If an encryption method is very robust and the key is unknown or compromised, decryption can be extremely difficult or practically impossible. The development and availability of decryption tools are often in a constant race with advancements in encryption techniques.
