Class Method Details

.sign(claims, options) ⇒ String

Returns a JSON Web Token, representing digitally signed claims.

Examples:

claims = {iss: 'joe', exp: 1300819380, :'http://example.com/is_root' => true}
options = {alg: 'HS256', key: 'gZH75aKtMN3Yj0iPS4hcgUuTwjAzZr9C'}
JsonWebToken.sign(claims, options)
# => 'eyJhbGciOiJIUzI1NiJ9.cGF5bG9hZA.uVTaOdyzp_f4mT_hfzU8LnCzdmlVC4t2itHDEYUZym4'

Parameters:

  • claims (Hash) —

    a collection of name/value pairs asserting information about a subject

  • options (Hash) —

    specify the desired signing algorithm and signing key

Returns:

  • (String) —

    a JSON Web Token, representing digitally signed claims

def sign(claims, options)
  Jwt.sign(claims, options)
end

.verify(jwt, options) ⇒ Hash

Returns a JWT claims set if the jwt verifies, or error: ‘Invalid’ otherwise.

Examples:

jwt = 'eyJhbGciOiJIUzI1NiJ9.cGF5bG9hZA.uVTaOdyzp_f4mT_hfzU8LnCzdmlVC4t2itHDEYUZym4'
options = {alg: 'HS256', key: 'gZH75aKtMN3Yj0iPS4hcgUuTwjAzZr9C'}
JsonWebToken.verify(jwt, options)
# => {iss: 'joe', exp: 1300819380, :'http://example.com/is_root' => true}

Parameters:

  • jwt (String) —

    a JSON Web Token

  • options (Hash) —

    specify the desired verifying algorithm and verifying key

Returns:

  • (Hash) —

    a JWT claims set if the jwt verifies, or error: ‘Invalid’ otherwise
