                    ECPrivateKey

Represents an elliptic curve private key.
Supported curves are:

prime256v1
secp384r1
NID_secp521r1
You can generate an elliptic curve Key using OpenSSL:
https://wiki.openssl.org/index.php/Command_Line_Elliptic_Curve_Operations#Generating_EC_Keys_and_Parameters

Usage Example:

let pemKey = """
-----BEGIN EC PRIVATE KEY-----
MHcCAQEEIJX+87WJ7Gh19sohyZnhxZeXYNOcuGv4Q+8MLge4UkaZoAoGCCqGSM49

KVmLgSSq2asqiwdrU5YHbcHFkgdABM1SPA==
-----END EC PRIVATE KEY-----
"""
let privateKey = try ECPrivateKey(key: pemKey)
let signature = "Hello world".sign(with: privateKey)

Declaration

Swift

public class ECPrivateKey


                    
                    
                    ECPublicKey

Represents an elliptic curve public key. Supported curves are:
