When generating a share link, look for the toggle option labeled . When this option is enabled, the person receiving the link will not be able to access the content until they also receive the decryption key, which you can send through a separate, more secure channel such as an encrypted messaging app or in person**** .
When a user uploads a file to MEGA, the following steps occur on the client device before any data leaves the user's computer. A new file key is generated using a cryptographically strong random number with entropy from both HTML5 APIs and mouse/keyboard entropy pools. The file is then encrypted with this file key using AES-128 in Counter (CTR) mode for the actual file data. For folder names and file names, AES-128 in Cipher Block Chaining (CBC) mode is used. The file key is then encrypted with the user's master key. Finally, both the encrypted file data and the encrypted file key are uploaded to MEGA's servers****.
The decryption key is appended to the URL after a # symbol. When someone clicks this link, their browser automatically uses that string to decrypt the file. decryption key mega.nz

No. Because MEGA does not store your keys, support representatives cannot reset your password or recover your data. If you lose both your password and your recovery key, the data is permanently lost. Why does MEGA use separate decryption keys for links? When generating a share link, look for the
If you are receiving a link with a key, always verify the source before downloading. If you are creating a key, share it through secure channels and revoke it when it is no longer needed. MEGA’s encryption is a fortress—but you hold the only key.
Given that your decryption keys are the gateway to your data, protecting them is paramount. A new file key is generated using a
A is a cryptographic string of 43 characters (usually letters, numbers, and symbols) that allows a user to unlock and decrypt a specific file or folder.
By default, when you share a link on MEGA, the decryption key is embedded directly into the URL. However, MEGA offers an important security feature: the ability to from the file link. This prevents anyone who intercepts just the link from accessing your data, as they would also need the separately transmitted key.
