SSH Ciphers

SSH Ciphers
Cipher
Description
AES (Advanced Encryption Standard)
A symmetric-key cipher widely used for secure data encryption. Provides strong encryption and is considered secure.
3DES (Triple Data Encryption Standard)
A symmetric-key block cipher that applies the Data Encryption Standard (DES) algorithm three times. It's relatively secure but less so than AES.
Blowfish
A symmetric-key block cipher known for its fast encryption and strong security. It's considered secure, though not as widely used as AES.
ChaCha20
A stream cipher designed for speed and security. It is known for being highly secure and efficient.
RSA (Rivest–Shamir–Adleman)
An asymmetric-key cipher used for public key encryption and digital signatures. RSA is widely used for key exchange in SSH.
DSA (Digital Signature Algorithm)
An asymmetric-key algorithm used for digital signatures. It's often used for SSH key authentication.
ECDSA (Elliptic Curve Digital Signature Algorithm)
An asymmetric-key algorithm that provides strong security with smaller key sizes, making it more efficient. Commonly used for SSH key authentication.
Ed25519
A specific implementation of the EdDSA (Edwards-curve Digital Signature Algorithm) for strong security and performance. It's gaining popularity for SSH key authentication.
