// ecdsa_vectors.js
// Data for testing ECDSA with every curve currently in the WebCryptoAPI recommendation.
// The following function returns an array of test vectors
// for the subtleCrypto encrypt method.
//
// Each test vector has the following fields:
// name - a unique name for this vector
// publicKeyBuffer - an arrayBuffer with the key data
// publicKeyFormat - "spki" "jwk"
// publicKey - a CryptoKey object for the keyBuffer. INITIALLY null! You must fill this in first to use it!
// privateKeyBuffer - an arrayBuffer with the key data
// privateKeyFormat - "pkcs8" or "jwk"
// privateKey - a CryptoKey object for the keyBuffer. INITIALLY null! You must fill this in first to use it!
// algorithmName - the name of the AlgorithmIdentifier parameter to provide to encrypt
// namedCurve - the curve used
// hashName - the hash function to sign with
// plaintext - the text to encrypt
// signature - the expected signature
