背景

$configuration = Configuration::forSymmetricSigner(
    // You may use any HMAC variations (256, 384, and 512)
    new Sha256(),
    // replace the value below with a key of your own!
    InMemory::base64Encoded('YWFhc0pOU0RLSkJITktKU0RiamhrMTJiM2Joa211')
    // You may also override the JOSE encoder/decoder if needed by providing extra arguments here
);

使用jwt生成秘密的时候，报错Key provided is shorter than 256 bits, only 240 bits provided

问题分析

使用InMemory::base64Encoded时密钥少了四位字符，导致生成的密钥长度只有240
