xml.CryptoKey.getEllipticCurveName

Returns the name of the elliptic curve for an ECDSA key, if available.

Syntax

getEllipticCurveName()
  RETURNS STRING

Usage

Returns the name of the elliptic curve associated with the loaded ECDSA key. The returned value will be one of the following strings, depending on the curve used:

secp256k1
secp256r1
prime256v1
secp384r1
secp521r1

Important: secp256r1

For secp256r1, the returned name will be prime256v1.

This method does not raise exceptions. If the key is not an ECDSA key or if no curve is associated, an empty string will be returned.

Example:

IMPORT xml
DEFINE key xml.CryptoKey
CALL key.loadPEM("ecdsa_private.pem")
DISPLAY key.getEllipticCurveName() -- e.g., "prime256v1"
