JSON Web Token Library

Library for encoding and decoding JSON web tokens for the MAC OS and Linux platforms.

Limitations

• It is not currently possible for windows
• The header is fixed to be {"alg": "HS256", "typ": "JWT"}

Compatible Platform

• MAC OS
• Linux

How To Use

• Build Library

    # project root path
    make && make install
    # it will build the library
    # and copy to $(projectRootPath)/output path 

• Build Example

    # project root path
    # cd to example path and compile
    cd example
    make && make install
    # it will build the jwt-test 
    # and copy to in $(projectRootPath)/output path 

• Test

    # when in $(projectRootPath)/output
    ./jwt-test

  it will output like below

    start jwt encode:
    username=test-user,PSK=12345678
    get jwt token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.dGVzdC11c2VyLDE2OTc1MjQzMDE.9atTOK9Y0WbSG0PmRddspYR6ffY8T7RfHQKenFQMT4Q
    start jwt decode...
