Example of Encryption

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

Encrypting an Object to Be Uploaded

Sample code:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret Key ***',       
    server : 'https://your-endpoint'
});

obsClient.putObject({
       Bucket: 'bucketname',
       Key: 'objectname',
       SourceFile: 'localfile',
        // Set the SSE-C encryption algorithm.  
       SseC: 'AES256',
// Use the original AES-256 character string, but not the key after Base64 encoding.
       SseCKey: 'your sse-c key generated by AES-256 algorithm'
}, function (err, result) {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});

obsClient.putObject({
       Bucket: 'bucketname',
       Key: 'objectname2',
       SourceFile: 'localfile2',
       // Set the SSE-KMS encryption algorithm.   
       SseKms: 'kms'
}, function (err, result) {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
       }
});

Decrypting a Downloaded Object

Sample code:

// Create an instance of ObsClient.
var obsClient = new ObsClient({
    access_key_id: '*** Provide your Access Key ***',       
    secret_access_key: '*** Provide your Secret Key ***',       
    server : 'https://your-endpoint'
});

obsClient.getObject({
       Bucket: 'bucketname',
       Key: 'objectname',
       // Set the SSE-C decryption algorithm.    
       SseC: 'AES256',
        // The key used here must be the one used for uploading the object.
       SseCKey: 'your sse-c key generated by AES-256 algorithm'
}, function (err, result) {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                     console.log('Content-->' + result.InterfaceResult.Content);     
              }
       }
});
