RSA

The RSA cryptography functions are provided under the crypt.rsa namespace.

---

generate_key_pair

function crypt.rsa.generate_key_pair(bits: number): (string, string)

Generates an RSA key pair.

Example

local public_key, private_key = crypt.rsa.generate_key_pair(2048)

---

encrypt

function crypt.rsa.encrypt(plaintext: string, public_key: string): string

Encrypts data using RSA public key.

Example

local encrypted = crypt.rsa.encrypt("Secret message", public_key)

---

decrypt

function crypt.rsa.decrypt(ciphertext: string, private_key: string): string

Decrypts RSA encrypted data using private key.

Example

local decrypted = crypt.rsa.decrypt(encrypted, private_key)

---

sign

function crypt.rsa.sign(data: string, private_key: string): string

Signs data using RSA private key.

Example

local signature = crypt.rsa.sign("Data to sign", private_key)

---

verify

function crypt.rsa.verify(data: string, signature: string, public_key: string): boolean

Verifies an RSA signature.

Example

local is_valid = crypt.rsa.verify("Data to verify", signature, public_key)
