Let’s talk about CSRF!
encodeSecret =
"4pE8z3PBoHjnV1AhvGk+e8h2p+ShZpOnpr8cwHmMh1w="
computeHMACSHA256(
header + "." + payload,
base64DecodeToByteArray(encodedSecret)
)
Signature Computation Pseudo-code
JWTSecret Anti-Patterns
.signWith( SignatureAlgorithm.HS256, "secret".getBytes("UTF-8") )
Short but not Sweet
String b64EncodedSecret = "Yn2kjibddFAWtnPJ2AFlL8WXmohJMCvigQggaEypa5E=";
.signWith(
SignatureAlgorithm.HS256,
b64EncodedSecret.getBytes("UTF-8")
)
You’re Doing it Wrong
String b64EncodedSecret = "Yn2kjibddFAWtnPJ2AFlL8WXmohJMCvigQggaEypa5E=";
.signWith(
SignatureAlgorithm.HS512,
TextCodec.BASE64.decode(b64EncodedSecret)
)
Supersize that Secret!
