JavaScript (sometimes abbreviated JS) is a scripting language commonly implemented as part of a web browser in order to create enhanced user interfaces and dynamic websites, but also used in other contexts (such as server-side JavaScript). PGP uses a combination of several encryption techniques applied serially, including symmetric-key and public-key cryptography. GNU Privacy Guard (GnuPG, GPG) is a commonly-used encryption tool using PGP format, running on Linux systems. Meanwhile, the specifications of the file format had been released as the OpenPGP spec and published as an RFC document, making it available for use in other products. Zimmerman's PGP company was eventually acquired by Network Associates (now McAfee), which eventually rebranded the original command-line-based PGP as "McAfee E-Business Server" and sold off all other PGP assets to some PGP developers who formed a new PGP company, which was eventually acquired by Symantec. These laws, while not completely repealed even now, have been considerably liberalized since, and now export of PGP and related software is only restricted when it's being exported to countries such as Iran that are under special sanction.
The list of MIME types and file extensions however is easily twice as long: application/pkcs8.p8.key application/ application/pkix-cert.cer application/pkix-crl.crl application/pkcs7-mime.p7c application/ application/x-x509-user-cert.crt application/x-pkcs7-crl.crl application/x-pem-file.pem application/ application/ application/ (Pretty Good Privacy) is an encryption program, and its encryption format which eventually became the OpenPGP standard.Ĭreated by Phil Zimmerman in 1991, it got into some legal trouble early on because encryption of this grade was classified as a munition under U.S. The way different items are encoded for transmission so that even software that was designed to work only with ASCII text can process the message.
The way in which each part of the message is specified.
MIME media types indicate the following things − How different parts of a message, such as text and attachments, are combined into the message. In HTML, this identifier can be useful for knowing the type of a file before downloading and being able to access it. Internet media types, formerly known as ' MIME types' or 'Content-types', is a standard designed to indicate the type of information a file or piece of data contains. This chapter is organized for the main types − text image multipart audio video message model application For example, the text main type contains types of plain text files, such as −. MIME content types consist of two parts − A main type A sub-type The main type is separated from the subtype by a forward slash character.
