Statics

CURVE-SECP256R1 -> any

Named constant for the "secp256r1" curve.

CURVE-SECP384R1 -> any

Named constant for the "secp384r1" curve.

CURVE-SECP521R1 -> any

Named constant for the "secp521r1" curve.

parse-private key/Data --password/string="" -> EcKey

Parses an EC private key and stores it as DER.

The key must be DER or PEM.

The password is optional and used for encrypted keys.

parse-public key/Data -> EcKey

Parses an EC public key and stores it as DER.

The key must be DER or PEM.

SHA-1 -> any

Produces a 20-byte digest.

SHA-256 -> any

Produces a 32-byte digest.

SHA-384 -> any

Produces a 48-byte digest.

SHA-512 -> any

Produces a 64-byte digest.

Methods

compute-shared-secret other-public-key/EcKey -> ByteArray

Computes a shared secret with the other-public-key.

This key must be a private key.

decrypt-ecies ciphertext/ByteArray -> ByteArray

Decrypts the given ciphertext using ECIES.

This key must be a private key.

operator == other/any -> bool

Whether this object is equal to the other.

By default, identical is used for equality.

Inheritance

Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:


class Pin:
  number/int

  constructor .number:

  operator == other:
    if other is not Pin: return false
    return number == other.number

A class doesn't have to follow the above format, but it must keep the operator in sync with any hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).

sign message/Data --hash/int=SHA-256 -> ByteArray

Signs the message with this private key.

sign-digest digest/ByteArray --hash/int -> ByteArray

Signs the digest with this private key.

size -> int

The size of the key DER in bytes.

stringify -> string

Stringifies this object.
