Use this option if you want to encode multiple independent data entries separated with line breaks. Encode each line separately: Even newline characters are converted to their Base64-encoded forms.For the files section, this is partially irrelevant since files already contain the corresponding separators, but you can define which one to use for the "encode each line separately" and "split lines into chunks" functions. Newline separator: Unix and Windows systems use different line break characters, so prior to encoding either variant will be replaced within your data by the selected option.As for files, the binary option is the default, which will omit any conversion this option is required for everything except plain text documents. Note that in case of text data, the encoding scheme does not contain the character set, so you may have to specify the appropriate set during the decoding process. Change this option if you want to convert the data to another character set before encoding. Character set: Our website uses the UTF-8 character set, so your input data is transmitted in that format.Base64 is used commonly in a number of applications including email via MIME, as well as storing complex data in XML or JSON. This encoding helps to ensure that the data remains intact without modification during transport. Base64 encode your data without hassles or decode it into a human-readable format.īase64 encoding schemes are commonly used when there is a need to encode binary data, especially when that data needs to be stored and transferred over media that are designed to deal with text. ![]() Just like our browser code, they are cryptographically sensitive, and we publish their source code in full.Meet Base64 Decode and Encode, a simple online tool that does exactly what it says: decodes from Base64 encoding as well as encodes into it quickly and easily. They are substantially less memory- and CPU-hungry, too! We therefore recommend installing our mobile app. MEGA links on iOS or Android automatically open the MEGA app and none of the difficulties arising in a browser context are relevant to native apps. Installing the MEGA Desktop App will allow your to circumvent such browser limitations when downloading files from MEGA. Chromium shines in this regard, and so we recommend that you use a Chromium-based browser: Google Chrome, Microsoft Edge (not the legacy version), Opera, Vivaldi, etc. Unfortunately, the writing to disk step is really tricky, as there is no standardised method that is supported by all browsers. Now, your browser fetches the encrypted file data from the server, decrypts it using the relevant key (which is only accessible through the anchor portion of the URL) and then writes the decrypted result to disk. When you start the download of a file, your browser cannot simply send the file’s key to the server for it to decrypt the download on your behalf – doing so would completely eviscerate zero-knowledge encryption. This JavaScript code is cryptographically sensitive and therefore must be public. When opening a MEGA file or folder link, the browser initially doesn’t receive any file or folder data – instead, it downloads a bunch of JavaScript code that then fetches the file or folder metadata and uses the decryption key from the anchor portion of the URL to decrypt it and display relevant file and folder information. ![]() Decrypt the downloaded file data in the browser.And that’s very handy when it comes to devising a URL format containing information that absolutely needs to stay on the client side: The key is included in the URL as a pseudo-anchor link, separated by a # character. Since the web server does not need to know about this, browsers do not send the anchor portion of a URL when requesting a page. Their original purpose was to link to locations within a page – the browser would automatically scroll to the page’s matching anchor point. And, how can an encrypted file be downloaded from a server that doesn’t have its decryption key? Here is how it works:Īnchor links are appended to a URL separated by a # symbol. In a browser context, two difficulties arise: How is the encryption key prevented from being sent to the MEGA servers when opening the link? If it was part of the HTTP request, zero-knowledge encryption would be compromised. This important cornerstone of our philosophy also applies to file and folder links. This means that all encryption and decryption is performed by our users, on their devices, with keys that only they have access to. MEGA is a zero-knowledge encryption cloud storage service.
