KeyPair class

Platform-agnostic RSA key pair representation.

This class provides a simple, serializable representation of an RSA key pair using PEM-encoded strings. Unlike platform-specific implementations (e.g., fast_rsa.KeyPair), this class can be safely used across all platforms including web workers and isolates.

Usage

final keyPair = KeyPair(
  '-----BEGIN PUBLIC KEY-----...',
  '-----BEGIN PRIVATE KEY-----...',
);

Security

The private key should be treated as sensitive data and handled securely:

• Never log or display private keys
• Store securely using platform-appropriate secure storage
• Transfer only within trusted boundaries (same application)

Constructors

KeyPair(String publicKey, String privateKey)

Creates a key pair from PEM-encoded strings.
