Generate a JSON Web Key (JWK)

A JSON object that represents a cryptographic key. The members of the object represent properties of the key, including its value.

Example JWK

{
      "kty":"EC",
      "crv":"P-256",
      "x":"f83OJ3D2xF1Bg8vub9tLe1gHMzV76e8Tus9uPHvRVEU",
      "y":"x_FEzRu9m36HLN_tue659LNpXW6pCyStikYjKIWI5a0",
      "kid":"Id that can be uniquely Identified"
  }

The kty (key type) parameter identifies the cryptographic algorithm family used with the key, such as RSA or EC

• RSA keys, prefred key Size 2048,4096, used for signature and encryption
• Elliptic curve keys: EC keys and EC operations with the following designations:
  • P-256 a.k.a secp256r1 (NIST) or prime256v1 (ANSI X9.62)
  • P-384 a.k.a secp384r1 (NIST)
  • P-521 a.k.a secp521r1 (NIST)
• Octet Key Pair : Octet key pairs are used to represent Edwards curve keys. They bear the JWK type designation “OKP” and are used for JSON Web Signatures (JWS) with Ed25519 / Ed448 and JSON Web Encryption (JWE) with ECDH with X25519 / X448
• Octet Sequence keys : The octet sequence JWK format is intended for representing secret keys, such as keys for use in HMAC and AES
  • HS256 : indicates that this token is signed using HMAC-SHA256
  • HS384
  • HS512
  • AES Keys
