createRSAPublicKey

public static RSAPublicKey createRSAPublicKey(String publicKeyPem)
                                       throws Exception

Creates a RSAPublicKey instance from its string PEM representation

Parameters:

publicKeyPem - the public key PEM string

Returns:

the RSA public key

Throws:

Exception - if it's not possible to create the RSA public key from the PEM string

createPublicKey

public static PublicKey createPublicKey(String publicKeyPem,
 String algorithm)
                                 throws Exception

Creates a PublicKey instance from its string PEM representation

Parameters:

publicKeyPem - the public key PEM string

algorithm - the key type (e.g. RSA)

Returns:

the public key

Throws:

Exception - if it's not possible to create the public key from the PEM string

isValid

public static boolean isValid(String token,
 PublicKey publicKey)
                       throws Exception

Verifies the token validity

Parameters:

token - the base64 JWT token string

publicKey - the realm's public key on server

Returns:

true if the token is valid, false otherwise

Throws:

Exception - if an error occurs constructing the verifier

isValid

public static boolean isValid(String token,
 PublicKey publicKey,
 boolean checkExpiration)
                       throws Exception

Verifies the token validity

Parameters:

token - the base64 JWT token string

publicKey - the public key to use for verification

checkExpiration - if false token expiration check is disabled

Returns:

true if the token is valid, false otherwise

Throws:

Exception - if an unexpected error occurs (e.g. constructing the verifier)

verify

public static void verify(String token,
 PublicKey publicKey)
                   throws org.gcube.io.jsonwebtoken.security.SignatureException,
org.gcube.io.jsonwebtoken.ExpiredJwtException,
org.gcube.io.jsonwebtoken.JwtException,
Exception

Verifies the token signature and expiration

Parameters:

token - the base64 JWT token string

publicKey - the public key to use for verification

Throws:

org.gcube.io.jsonwebtoken.security.SignatureException - if the token signature is invalid

org.gcube.io.jsonwebtoken.ExpiredJwtException - if the token is expired

org.gcube.io.jsonwebtoken.JwtException - if a JWT related problem is found

Exception - if an unexpected error occurs (e.g. constructing the verifier)
