generateEncryptionDecryptionKeyPair

Generates a keypair for encrypting/decrypting keyshare backups.

Use this to create encryption keys for secure keyshare export/import operations. The encryption key should be kept secure, while the decryption key can be shared with other parties for import operations.

Example:

// Generate encryption keys for backup
val (encryptionKey, decryptionKey) = SilentShard.ECDSA.generateEncryptionDecryptionKeyPair()

// Export keyshare
val exportedData = session.export(keyshare).getOrThrow()

// Store exported data securely
secureStorage.save(exportedData)
