Description
I am trying to integrate zoom API with the Spring Boot application, If I use the JWT token created online and hard code it in the application I am able to send a request to the meeting creation API and create a new meeting successfully. I want to automate the JWT creation process but the JWT creation method throws an error and JWT creation fails and leads to application failure
Error
The specified key byte array is 136 bits which is not secure enough for any JWT HMAC-SHA algorithm. The JWT JWA Specification (RFC 7518, Section 3.2) states that keys used with HMAC-SHA algorithms MUST have a size >= 256 bits (the key size must be greater than or equal to the hash output size). Consider using the io.jsonwebtoken.security.Keys#secretKeyFor(SignatureAlgorithm) method to create a key guaranteed to be secure enough for your preferred HMAC-SHA algorithm. See https://tools.ietf.org/html/rfc7518#section-3.2 for more information.

How To Reproduce (If applicable)
Steps to reproduce the behavior:
private String generateZoomJWTToken(){
String id = UUID.randomUUID().toString().replace("-", “”);
SignatureAlgorithm signatureAlgorithm = SignatureAlgorithm.HS256;
Date creation = new Date(System.currentTimeMillis());
Date expiry = new Date(System.currentTimeMillis()+(1000*60));
SecretKey key =
Keys.hmacShaKeyFor(zoomApiSecret.getBytes(StandardCharsets.UTF_8));//This line throws error
return Jwts.builder()
.setId(id)
.setIssuer(zoomApiKey)
.setIssuedAt(creation)
.setSubject("")
.setExpiration(expiry)
.signWith(key,signatureAlgorithm)
.compact();
}
