Asymmetric-key algorithms use a combination of private and public keys while symmetric algorithms use only private ones, commonly referred to as secret keys.

Symmetric algorithms convert plain-text data into an unreadable ciphertext using a single key or password; they decrypt the ciphertext using the same key.

The result of this requirement is a much larger key size than symmetric-key algorithms for an equivalent amount of security. As an example, 512-bit RSA is considered to be about the same level of ...

Symmetric and asymmetric security Communication channels are often secured using cryptographic algorithms. Broadly speaking, cryptographic algorithms can be classified as symmetric and asymmetric.

It’s a symmetric key algorithm, so there’s one flaw with it. It’s not just the government, either: militaries, banks, and corporations across the world trust AES-256 to keep their data secure ...

For the last half century the principal encryption method was symmetric key, i.e., the use of the same algorithm to encrypt and decrypt by using the same key at the encryptor and decryptor.

Asymmetric algorithms use different keys — one public, one private — to validate two parties’ identities and then to securely establish the shared secret (symmetric) key between them.

The file data is then encrypted with a symmetric algorithm called as DESX. Encrypting File System (EFS) The key used for these kinds of symmetric encryption is called as File Encryption Key (or FEK).
