crypto.publicEncrypt()

crypto.publicEncrypt(public_key, buffer)

Encrypts buffer with public_key.

public_key can be an object or a string. If public_key is a string, it is treated as the key with no passphrase and will use RSA_PKCS1_OAEP_PADDING. If public_key is an object, it is interpreted as a hash object with the keys:

• key : {String} - PEM encoded public key
• passphrase : {String} - Optional passphrase for the private key
• padding : An optional padding value, one of the following:
  • constants.RSA_NO_PADDING
  • constants.RSA_PKCS1_PADDING
  • constants.RSA_PKCS1_OAEP_PADDING

Because RSA public keys can be derived from private keys, a private key may be passed instead of a public key.

All paddings are defined in the constants module.
