How to decrypt JWE(Json Web Encryption) data using private key in java
I have a private key similar to below
e.g.
-----BEGIN PRIVATE KEY-----
MIIEvQIBADANBgkqhkiG9w0BAQEFAASCBKcwggSjAgEAAoIBAQDGBRdsiDqKPGyH
gOpzxmSU2EQkm+zYZLvlPlwkwyfFWLndFLZ3saxJS+LIixsFhunrrUT9ZZ0x+bB6

-----END PRIVATE KEY-----
I have a JWE data as below which was encrypted using the public key generated from above private key/certificate
aaaaa.bbbbb.ccccc.ddddd.eeeee
Can someone give me java code I can use to decrypt this JWE using my private key? I cannot find a clear answer from internet. I am kind if new to this JWE concept
Answer
Due to your other question and tags to this question, I assume you chose the library Nimbus JOSE + JWT. Regardless of your Framework for JWT, I advise you to use the provided way to encrypt/decrypt your tokens, because they validate the structure of the token.
RSAPrivateKey privateKey; //initialize with your key
String jwtTokenAsString = "aaaaa.bbbbb.ccccc.ddddd.eeeee"; //your token
EncryptedJWT encryptedJWT = EncryptedJWT.parse(jwtTokenAsString);
RSADecrypter decrypter = new RSADecrypter(privateKey);
encryptedJWT.decrypt(decrypter);
//Access content with diffrent methods
JWTClaimsSet claims = encryptedJWT.getJWTClaimsSet();
Payload payload = encryptedJWT.getPayload();
