How to Encrypt + Decrypt Text Files - UltraEdit (2024)

FAQs

How to encrypt and decrypt a text file? ›

As a good rule of thumb, you need to encrypt any file that contains sensitive or confidential information, whether it's legal or financial, business, or personal. This can include personal identification information, financial details, medical records, trade secrets, and more.

Right-click on the encrypted file or folder and select “Properties.” In the “Properties” window, navigate to the “General” tab. Locate the “Encrypt contents to secure data” option. Uncheck this option to initiate the decryption process.

The best encryption for files depends on the specific use case and requirements. AES-256 is considered one of the most secure and commonly used encryption algorithms. Although for most practical purposes, AES-128 will do just as well.

Anyone can encrypt a message by using your public key, but only you can read it. When you receive the message, you decrypt it by using your private key. Similarly, you can encrypt a message for anyone else by using their public key, and they decrypt it by using their private key.

These encryption systems use both a public key and a private key. Anyone with the public key can use it to encrypt files. However, only users with the private key can decrypt the files, so the files remain safe from unauthorized access. Symmetric encryption uses a single private key for encryption and decryption.

Legal documents: Contracts, legal agreements, and other sensitive legal files should be encrypted to maintain confidentiality. Business data: Company plans, strategies, intellectual property, and confidential client or customer information require encryption to protect against competitors and data breaches.

Yes, an encrypted file can be encrypted multiple times, but this does not guarantee an increase the security. If the algorithm in use is AES with a suitable mode (eg, CTR, CFB, CBC, GCM, EAX etc.), then yes, but the process will be twice as slow. It is better to use AES-256 once than using AES-128 twice.

How to decrypt encrypted files after formatting? ›

AES 256-bit encryption is the strongest and most robust encryption standard that is commercially available today. While it is theoretically true that AES 256-bit encryption is harder to crack than AES 128-bit encryption, AES 128-bit encryption has never been cracked.

After the data is converted from plaintext to ciphertext, it can be decoded only through the use of the proper key. This key might be the same one used for encoding the data or a different one, depending on the type of algorithm -- symmetric or asymmetric. If it's a different key, it's often called a decryption key.

Encryption is the process by which a readable message is converted to an unreadable form to prevent unauthorized parties from reading it. Decryption is the process of converting an encrypted message back to its original (readable) format. The original message is called the plaintext message.

Yes, there are numerous apps available that allow you to send encrypted text messages. Examples include Signal, WhatsApp, and more, which use end-to-end encryption. This means that only you and the person you're communicating with can read what's sent.

Symmetric key: Your system has a key for encryption/decryption. Move your password through this key to scramble it, and push it back through the key to make it readable once more. A hacker must steal the key to take over your password. Public key: Two keys play a role in altering your password.
