How to Encrypt and Decrypt a File
- Create a symmetric key of the appropriate length. You have two options. You can provide a passphrase from which a key will be generated.
- Encrypt a file. Provide a key and use a symmetric key algorithm with the encrypt command.
How the data are encrypted?
Data, or plaintext, is encrypted with an encryption algorithm and an encryption key. The process results in ciphertext, which only can be viewed in its original form if it is decrypted with the correct key. Symmetric-key ciphers use the same secret key for encrypting and decrypting a message or file.
How does one decrypt or access encrypted data?
For the ciphertext to be transformed to plaintext, the decryption function must use the same cryptographic key used by the encryption function to decrypt the ciphertext. If the cryptographic key is modified, the plaintext cannot be reproduced. When this happens, the plaintext (the protected data) is lost.
How is data encrypted during storage?
It is the method by which a plaintext or any type of data is encoded. The encoded data can only be decoded by the person who has the decryption key. This method keeps the data protected. The encrypted data is commonly referred to as the cipher text, while unencrypted data is called plain text.

What is data encryption and why is it important?
Encryption is the act of encoding data to render it unintelligible to someone who doesn’t have the authorization to access the data. Once data is encrypted, only authorized parties who have a “key” can read it or use it. That is, if the encryption method is effective, it should completely protect data from unauthorized access.
How does encryption help to protect data?
Data encryption protects data wherever it lives across the hybrid multicloud environment. Once data is encrypted and the encryption key is secured, the data becomes useless to any cybercriminal. If that data is already encrypted, that makes it much more difficult for the malware to detect it and attack.
What is encryption and how does it work?
Encryption works by scrambling the original message with a very large digital number (key). This is done using advanced mathematics. Commercial-level encryption uses 128 bit key that is very, very hard to crack. The computer receiving the message knows the digital key and so is able to work out the original message.
What are the different methods of encryption?
– Symmetric Encryption. Symmetric encryption’s job is to take readable data (“plaintext” in crypto parlance), scramble it to make it unreadable (protecting it from prying eyes while it’s being stored on – Asymmetric Encryption. – Hashing. – The Weakest Link.
