Text Encryptor

Online Text Encryptor

Automatically encrypt or decrypt text using many different algorithms with this text encryptor web app. Paste any text document into the text box, choose your passwords and encryption algorithm, then click encrypt to receive the encrypted text. Make sure to save the passwords, algorithm used and encrypted text, you will need all of it to decrypt the results later and view the original message.

Use this app to encrypt any text document, such as an email, pdf, secret memo, confidential or classified information, love letter, etc, and save that message or securely send it to someone. For the most success, you should send the two password values and algorithm separately from the message and through an alternate secure means (preferably in person).

Encrypting and Decrypting Text

When you use this app to encrypt text, you can either choose the two passwords yourself, or preferably just leave them blank. The text encryptor will automatically generate a "key" (Password 1) and an "IV" (Password 2) - which stands for Initialization Vector. It's easiest to just think of them as two passwords which secure the encrypted data with an algorithm. You can create a stronger password #1 (the key) if you'd like - up to 1000 characters - but password #2 (the IV) must be exactly 16 characters long and is best to leave blank.

When decrypting, simply chose the decrypt option and paste the encrypted data in the textbox, enter the passwords, and chose the correct algorithm. The original text will be output to the results.

Encrypt Text using Strong Algorithms

With this free online text encryptor, you can encrypt your message with a variety of cyphers, the default algorithm being AES-256-CBC. AES-256-CBC is currently a leading algorithm that is even used by the US Government to secure classified information. As this default algorithm is so strong and fast, there really is little reason to use the others, except for experimentation and testing. For more information on AES (Advanced Encryption Standard) and its design principles of substitution-permutation see this biclique cryptanalysis article and this AES article. Using this app you can ecrypt text with the following alogorithm option: AES-128-CBC, AES-128-CFB, AES-128-CFB1, AES-128-CFB8, AES-128-OFB, AES-192-CBC, AES-192-CFB, AES-192-CFB1, AES-192-CFB8, AES-192-OFB, AES-256-CFB, AES-256-CFB1, AES-256-CFB8, AES-256-OFB, CAMELLIA-128-CBC, CAMELLIA-128-CFB1, CAMELLIA-128-CFB8, CAMELLIA-128-OFB, CAMELLIA-192-CBC, CAMELLIA-192-CFB, CAMELLIA-192-CFB1, CAMELLIA-192-CFB8, CAMELLIA-192-OFB, CAMELLIA-256-CBC, CAMELLIA-256-CFB, CAMELLIA-256-CFB1, CAMELLIA-256-CFB8, CAMELLIA-256-OFB, SEED-CBC, SEED-CFB and SEED-OFB.

More about using a Text encryptor

In a world of ever concerning security risks - whether it be foreign governments, hackers, your own government, agencies like the NSA, etc, security and encryption tools like this are becoming ever more important for your privacy, safety and freedom. Protect yourself and your valuable information by encrypting your data, your messages, emails, text documents with this online encryption tool. Whether you encrypt personal data for long term storage or encrypt email messages to send to recipients, this encryption tool can be useful.

Essentially in cryptography, encryption is the converting of a message or data from a readable form into an obscure and unreadable form. The goal is security, so that only authorized people are able to decipher the message. Various types of encryption exists, but what is available in this tool is called two-way symmetric/private-key encryption. A certain key (or keys in this case) are used to encrypt the data, and the same keys are used to decrypt the data and is meant to be kept secret.
