Examples with SecureRandom java.security.SecureRandom used on opensource projects

Example 26 with SecureRandom

use of java.security.SecureRandom in project sonarqube by SonarSource.

the class JwtCsrfVerifier method generateState.

public String generateState(HttpServletRequest request, HttpServletResponse response, int timeoutInSeconds) {
    // Create a state token to prevent request forgery.
    // Store it in the cookie for later validation.
    String state = new BigInteger(130, new SecureRandom()).toString(32);
    response.addCookie(newCookieBuilder(request).setName(CSRF_STATE_COOKIE).setValue(state).setHttpOnly(false).setExpiry(timeoutInSeconds).build());
    return state;
}

Example 27 with SecureRandom

use of java.security.SecureRandom in project sonarqube by SonarSource.

the class OAuthCsrfVerifier method generateState.

public String generateState(HttpServletRequest request, HttpServletResponse response) {
    // Create a state token to prevent request forgery.
    // Store it in the session for later validation.
    String state = new BigInteger(130, new SecureRandom()).toString(32);
    response.addCookie(newCookieBuilder(request).setName(CSRF_STATE_COOKIE).setValue(sha256Hex(state)).setHttpOnly(true).setExpiry(-1).build());
