JWS

JSON Web Signature (JWS) represents content secured with digital signatures or Message Authentication Codes (MACs) using JSON based data structures

JWS HMAC Algo

• HS256 - HMAC with SHA-256, requires 256+ bit secret
• HS384 - HMAC with SHA-384, requires 384+ bit secret
• HS512 - HMAC with SHA-512, requires 512+ bit secret

JWS RSA Algo

• RS256 - RSA PKCS#1 signature with SHA-256
• RS384 - RSA PKCS#1 signature with SHA-384
• RS512 - RSA PKCS#1 signature with SHA-512
• PS256 - RSA PSS signature with SHA-256
• PS384 - RSA PSS signature with SHA-384
• PS512 - RSA PSS signature with SHA-512

JWS Elliptic Curve (EC) Algo

• ES256 - EC P-256 DSA with SHA-256
• ES384 - EC P-384 DSA with SHA-384
• ES512 - EC P-521 DSA with SHA-512
