The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256

by

AWS4-HMAC-SHA256, also known as Signature Version 4, (“V4”) is one of two authentication schemes supported by S3. All regions support V4, but US-Standard¹, and many — but not all — other regions, also support the other, older scheme, Signature Version 2 (“V2”). According to http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html … new S3 regions deployed after January, 2014 will only … Read more

Technically what is the difference between s3n, s3a and s3?

by

The letter change on the URI scheme makes a big difference because it causes different software to be used to interface to S3. Somewhat like the difference between http and https – it’s only a one-letter change, but it triggers a big difference in behavior. The difference between s3 and s3n/s3a is that s3 is … Read more

Getting Access Denied when calling the PutObject operation with bucket-level permission

by

To answer my own question: The example policy granted PutObject access, but I also had to grant PutObjectAcl access. I had to change “s3:PutObject”, “s3:GetObject”, “s3:DeleteObject” from the example to: “s3:PutObject”, “s3:PutObjectAcl”, “s3:GetObject”, “s3:GetObjectAcl”, “s3:DeleteObject” You also need to make sure your bucket is configured for clients to set a public-accessible ACL by unticking these … Read more

How to write a file or data to an S3 object using boto3

In boto 3, the ‘Key.set_contents_from_’ methods were replaced by Object.put() Client.put_object() For example: import boto3 some_binary_data = b’Here we have some data’ more_binary_data = b’Here we have some more data’ # Method 1: Object.put() s3 = boto3.resource(‘s3’) object = s3.Object(‘my_bucket_name’, ‘my/key/including/filename.txt’) object.put(Body=some_binary_data) # Method 2: Client.put_object() client = boto3.client(‘s3′) client.put_object(Body=more_binary_data, Bucket=”my_bucket_name”, Key=’my/key/including/anotherfilename.txt’) Alternatively, the binary … Read more

Quick way to list all files in Amazon S3 bucket?

by

I’d recommend using boto. Then it’s a quick couple of lines of python: from boto.s3.connection import S3Connection conn = S3Connection(‘access-key’,’secret-access-key’) bucket = conn.get_bucket(‘bucket’) for key in bucket.list(): print(key.name.encode(‘utf-8’)) Save this as list.py, open a terminal, and then run: $ python list.py > results.txt

Amazon S3 direct file upload from client browser – private key disclosure

by

I think what you want is Browser-Based Uploads Using POST. Basically, you do need server-side code, but all it does is generate signed policies. Once the client-side code has the signed policy, it can upload using POST directly to S3 without the data going through your server. Here’s the official doc links: Diagram: http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingHTTPPOST.html Example … Read more

Amazon S3 – HTTPS/SSL – Is it possible? [closed]

by

This is a response I got from their Premium Services Hello, This is actually a issue with the way SSL validates names containing a period, ‘.’, > character. We’ve documented this behavior here: http://docs.amazonwebservices.com/AmazonS3/latest/dev/BucketRestrictions.html The only straight-forward fix for this is to use a bucket name that does not contain that character. You might instead … Read more
