(async, static) encrypt(data, n, e) → {Promise.<Uint8Array>}
Encrypt message
Parameters:
| Name | Type | Description |
|---|---|---|
data |
Uint8Array | Message |

(async, static) generate(bits, e) → {Object}
Generate a new random private key B bits long with public exponent E.
When possible, webCrypto or nodeCrypto is used. Otherwise, primes are generated using 40 rounds of the Miller-Rabin probabilistic random prime generation algorithm.
Parameters:
| Name | Type | Description |
|---|---|---|
bits |
Integer | RSA bit length |
e |
Integer | RSA public exponent |

- module:crypto/public_key/prime
Returns:
RSA public modulus, RSA public exponent, RSA private exponent, RSA private prime p, RSA private prime q, u = p ** -1 mod q
- Type
- Object
