Asymmetric Cryptography

Learn about public-key cryptography and try RSA encryption with our interactive tools

What is Asymmetric Cryptography?

Asymmetric cryptography uses two different keys: a public key for encryption and a private key for decryption. The public key can be shared openly, while the private key must be kept secret. This solves the key distribution problem.

Popular Algorithms

RSA (Rivest-Shamir-Adleman)

ECC (Elliptic Curve Cryptography)

DSA (Digital Signature Algorithm)

Advantages

• Solves key distribution problem
• Provides digital signatures
• Enables non-repudiation
• No shared secret needed

Disadvantages

• Slower than symmetric encryption
• Larger key sizes required
• More complex implementation
• Higher computational overhead
