问题 I recently upgraded from PyJWT 0.4.1 to 1.0.1 and I can't figure out how to verify a JWT signed with a public key. My code looks like this: import jwt cert_string = "-----BEGIN CERTIFICATE-----\nMIICITCCAYqgAwIBAgIIBEsUSxL..." token_string = "eyJhbGciOiJSUzI1NiIsImtpZCI6I..." jwt.decode(token_string, cert_string, algorithms=['RS256']) The error I get is: File "<stdin>", line 1, in <module> File "~/.virtualenvs/project/lib/python2.7/site-packages/jwt/api.py", line 117, in decode key,

在做苹果推送，发现本地路径的key是没有问题，只要放到工程里编译完就报错，后来查询发现maven的插件给篡改了密钥key，所以通过在pom.xml文件里进行过滤，即保持原来的密钥key，就成功了，以下文件 < plugin > < groupId > org.apache.maven.plugins </ groupId > < artifactId > maven-resources-plugin </ artifactId > < configuration > < encoding > UTF-8 </ encoding >  < nonFilteredFileExtensions > < nonFilteredFileExtension > pem </ nonFilteredFileExtension > < nonFilteredFileExtension > pfx </ nonFilteredFileExtension > < nonFilteredFileExtension > p12 </ nonFilteredFileExtension > </ nonFilteredFileExtensions > </ configuration > </ plugin > 来源： CSDN 作者： XingAmanda

先摘抄网上的一部分，一定要看完哦！开发微信支付接口需要用到公钥和私钥，密钥文件统一放到项目src/main/resources的某个目录下，然后打包部署到测试环境的jboss，发起支付或退款，失败了。报错：DerInputStream.getLength(): lengthTag=111, too big. 如果把证书单独放到某个文件目录下是木有问题的，猜测是否是路径太长导致的呢？在本地测试排除了这个可能性，然后再网上找资料发现该异常时由于证书加载不正确导致，那就说明证书被修改过。为了证实这种情况，我把maven打好的war中的证书文件替换掉，果然是这个原因。那证书为什么会被修改呢，原来就是maven-resources-plugin作怪。 <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <configuration> <encoding>UTF-8</encoding>  <nonFilteredFileExtensions> <nonFilteredFileExtension>pem</nonFilteredFileExtension>
