GenerateAsymmetricKeyPair

GenerateAsymmetricKeyPair[]

randomly generates a PrivateKey and corresponding PublicKey object for use with public-key cryptographic functions.

GenerateAsymmetricKeyPair[type]

randomly generates private and public keys of the specified type.

GenerateAsymmetricKeyPair[opts]

randomly generates keys using the specified options.

Details and Options

  • GenerateAsymmetricKeyPair returns an association of the form <|"PrivateKey"…,"PublicKey" …|>.
  • GenerateAsymmetricKeyPair[] by default uses the "RSA" type, with a system-specific, high-entropy randomness source.
  • In GenerateAsymmetricKeyPair[type], the following types can be specified:
  • "RSA"RSA with default parameters
    "EllipticCurve"elliptic curve secp256k1
    "EdwardsCurve"twisted Edwards curve ed25519
    "Bitcoin","Ethereum"keys suitable for blockchains
    Method"curve" named elliptic curve
  • GenerateAsymmetricKeyPair has the following option:
  • MethodAutomaticdetails of key generation method
  • With the setting Method->assoc, the association assoc gives details of the key generation method to use.
  • The following element should be included in the association:
  • "Type""RSA"type of keys to produce
  • Possible settings for "Type" are "RSA" , "EllipticCurve" and "EdwardsCurve".
  • For "RSA", the following elements can be given in the association:
  • "KeySize"2048target size of key in bits
    "PublicExponent"65537public exponent
  • For "EllipticCurve", the following elements can be given in the association:
  • "CurveName""secp256k1"elliptic curve to use
    "Compressed"Falsewhether the public key is in compressed form
  • For "EdwardsCurve", the following elements can be given in the association:
  • "CurveName""ed25519"twisted Edwards curve to use
  • Possible settings for "CurveName" and Methodcurve are listed in $CryptographicEllipticCurveNames.
  • "Bitcoin" uses "CurveName""secp256k1" and "Compressed"True.
  • "Ethereum" uses "CurveName""secp256k1" and "Compressed"False.
