What is a .ASC file?
An .ASC file is a type of text file that uses ASCII formatting. ASCII stands for American Standard Code for Information Interchange, which is a common format for text files in computers. The .ASC file is specifically used by a program called Pretty Good Privacy (PGP), which is designed to make communications secure. PGP encrypts messages so that only the intended recipient can read them, and .ASC files are often used to hold these encrypted messages.
The contents of an .ASC file can include plain text, which is just normal readable text, or it can include binary information (like pictures or sounds) that has been turned into text using a special encoding method. This makes it possible to send different types of data securely as text. Additionally, .ASC files contain a digital signature, which helps verify that the message really comes from the person it claims to be from and that it hasn't been tampered with.
To open an .ASC file, you can use several programs: - GnuPG, which is a free software for encryption. - Mozilla Thunderbird with the Enigmail plug-in, which is an email program that can handle encrypted messages. - Mozilla SeaMonkey with the Enigmail plug-in, which is a web browser that also handles email and can work with encrypted messages. - Gpg4win, which is another free encryption software that works on Windows.
These programs help you decrypt the .ASC file to read the message or verify the sender using the digital signature.
.ASC files are particularly useful for sending secure emails or posting security notices online where verifying the authenticity of the message is important. Because .ASC files can turn binary data into text, they might be larger than the original files. However, this size increase is a small price to pay for the added security and verification capabilities.
In 2010, the company Symantec acquired PGP, and now PGP is part of Symantec's Enterprise Security Group, which continues to support and develop secure communication tools.
