Using hardcoded cryptographic key when creating and verifing Json Web Token. #10

Description

@xubowenW

Hi, we are a research group to help developers build secure applications. We designed a cryptographic misuse detector on Java language(Our main concern is the secure implementation and use of Json Web Token). We found your great public repository (i.e.,BaseProject) from Github, and several security issues detected by our detector are shown in the following. The specific security issues we found are as follows:
(1) Location: Package: org.apache.commons.codec.binary.Base64; Class: generalKey.class
Security issue: Using predictable/constant seed to generate cryptographic key when creating and verifing Json Web Token.

Using a hard-coded seed to generate key [(new SecretKeySpec(encodedKey, 0, encodedKey.length, "AES");] does not conform to the security implementation specification of JWT, which may bring security risks to your system. It is recommended that you use a more secure way to generate the key used to generate the JWT. (For the hazards of hardcoded keys, you can refer to CWE-321, NIST Special Publication 800-57).

We wish the above security issues cloud truly help you to build a secure application. If you have any concern or suggestion, please feel free to contact us, we are looking forwart to your reply. Thanks.

                              Using hardcoded cryptographic key when creating and verifing Json Web Token. #10

                              Description

                              @xubowenW

                              Hi, we are a research group to help developers build secure applications. We designed a cryptographic misuse detector on Java language(Our main concern is the secure implementation and use of Json Web Token). We found your great public repository (i.e.,BaseProject) from Github, and several security issues detected by our detector are shown in the following. The specific security issues we found are as follows:
                              (1) Location: Package: org.apache.commons.codec.binary.Base64; Class: generalKey.class
                              Security issue: Using predictable/constant seed to generate cryptographic key when creating and verifing Json Web Token.

                              Using a hard-coded seed to generate key [(new SecretKeySpec(encodedKey, 0, encodedKey.length, "AES");] does not conform to the security implementation specification of JWT, which may bring security risks to your system. It is recommended that you use a more secure way to generate the key used to generate the JWT. (For the hazards of hardcoded keys, you can refer to CWE-321, NIST Special Publication 800-57).

                              We wish the above security issues cloud truly help you to build a secure application. If you have any concern or suggestion, please feel free to contact us, we are looking forwart to your reply. Thanks.
