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:
// Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use source codes to install the client.
// var ObsClient = require('./lib/obs');
// 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',
SseCKey: 'your sse-c key generated by AES-256 algorithm'
}, (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'
}, (err, result) => {
if(err){
console.log('Error-->' + err);
}else{
console.log('Status-->' + result.CommonMsg.Status);
}
});
Decrypting a Downloaded Object
Sample code:
// Import the OBS library.
// Use npm to install the client.
var ObsClient = require('esdk-obs-nodejs');
// Use source codes to install the client.
// var ObsClient = require('./lib/obs');
// 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'
}, (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.toString());
}
}
});
