MASV is a large file transfer service that lets creative professionals safely send and receive copyrighted material without the worry of data breaches. This is also often called “SSL/TLS encryption”.Įither way, at this point, it almost goes without saying that you can’t expect guaranteed secure file transfer without a strong encryption element. Modern websites often use TLS encryption (its existence on a website is identifiable by the little padlock in the URL bar of your browser), which is an improved version of legacy “secure socket layer” (SSL) encryption. Among these, various encryption algorithms or ciphers exist including Data Encryption Standard ( DES ), Triple DES, RSA, Transport Layer Security ( TLS ), Advanced Encryption Standard ( AES ), Serpent, Camellia, Kuznyechik, and Twofish. Two main types of encryption exist: symmetric (which uses a single key for encryption and decryption) and asymmetric (which uses a public key to encrypt data and a private key for decryption). Under E2EE, only the sender and receiver can access the cryptographic key, while other types of encryption often render these keys readable by your email, telecom, internet, and cloud storage providers (along with the bad actors who sometimes hack these providers). These algorithms can be decrypted using a unique encryption key.

At its most basic, file encryption converts messages or files into unreadable code (encrypted data is known as ciphertext, while unencrypted data is called plaintext) through algorithms that scramble the data. Some email services, such as ProtonMail, include E2EE but also come with hard file size limits, limiting their usefulness for sending large files.Įncryption is vital for safe and secure file transfer. Įnd-to-end encryption (E2EE), which ensures that only you (and not even your provider) can read your emails, isn’t available in most consumer-grade email platforms. You can tweak Gmail’s settings to ensure all messages are transmitted securely, but it’s complicated. For example, in the case of Gmail, it doesn’t work when sending an email to someone using an email service that doesn’t support TLS (these messages are typically sent via an insecure connection). While most modern email services now support TLS encryption, there are a few catches. “Anyone with access to an intermediate mail server or with the ability to sniff network traffic between our mail servers would see. “Email is not designed to be secure,” says IT security expert Susan Hinrichs.

Sending files by email is convenient and easy-practically everyone knows how to send an email and add an attachment-but also pretty risky in most cases.
