此处D是解密(Decryption)的首字母;N是数字(Number)的首字母。 生成密钥对: 既然公钥是(E,N),私钥是(D,N),所以密钥对即为(E,D,N),但密钥对是怎样生成的?步骤如下: 求N 求L(L为中间过程的中间数) 求E 求D1)求N: 准备两个互质数p,q。这两个数不能太小,太小则会容易破解,将p乘以q就是N。如果...

So which key do we use for decryption? If the jwe was encrypted directly with a SecretKey, the same SecretKey must be specified on the JwtParserBuilder. For example: Jwts.parser() .decryptWith(secretKey) // <--- .build() .parseEncryptedClaims(jweString); If the jwe was encrypted usi...
