What is RSA Decryption?

RSA Decryption uses the private key to recover the original plaintext from RSA-encrypted ciphertext.

How to Use RSA Decryption

When to Use RSA Decryption

How RSA Decryption Works

Decryption uses the private key (n, d) to perform modular exponentiation on the ciphertext, reversing the encryption process.

Common Use Cases

  • Decrypt encrypted messages
  • Verify encryption
  • Secure communications

FAQs

1 Can I decrypt without the private key?

No, RSA security relies on keeping the private key secret. Without it, decryption is computationally infeasible.
