Encrypted file transfer definition

Encrypted file transfer is a secure way of sharing files from one device to another or using a network to ensure the confidentiality and integrity of the data. When you encrypt a file, the information inside is in an unreadable format that can become only readable again by using a decryption key or a password. The sender and receiver are the only ones who have it. Encryption helps prevent access from unauthorized parties, viruses, or other types of malware. It is essential to encrypt files that contain sensitive data such as personal information, confidential business data, or financial records.

Types of encryption

  • Symmetric encryption. A type of encryption where the same key encrypts and decrypts the data. When doing this, the sender and the recipient must ensure they share the information about the key safely and keep it a secret. Symmetric encryption is best for quickly sharing large amounts of data.
  • Asymmetric encryption. A type of encryption that uses two separate keys for encryption and decryption. Anyone can use the public key to encrypt the data. However, only the key pair owner knows the private key that decrypts the data. Asymmetric encryption is best for sharing digital signatures and secure communication.
