The multipart upload initiate requested encryption.

[rokka-n]

Am I doing something stupid?

creds = Aws::SharedCredentials.new(region: 'us-east-1')
s3 = Aws::S3::Resource.new(creds, :region => 'us-east-1')

cipher = OpenSSL::Cipher::AES256.new(:CBC)
key = cipher.random_key
obj = s3.bucket('some-backups').object('key')

obj.upload_file('large.txt', :sse_customer_key => key, :sse_customer_algorithm=>'AES256')

/Library/Ruby/Gems/2.0.0/gems/aws-sdk-resources-2.2.14/lib/aws-sdk-resources/services/s3/multipart_file_uploader.rb:72:in `abort_upload': multipart upload failed: The multipart upload initiate requested encryption. Subsequent part requests must include the appropriate encryption parameters

from aws-sdk-ruby/aws-sdk-resources/lib/aws-sdk-resources/services/s3/multipart_file_uploader.rb:72:in `abort_upload'

It repeats the message for all parts of upload.

Hi,

Looks like a bug.

There is a bunch of options missing in the compute_parts method at

aws-sdk-ruby/aws-sdk-resources/lib/aws-sdk-resources/services/s3/multipart_file_uploader.rb

Line 87 in 282f971

parts << {

Since "part" object is missing some parameters, upload_part fails in cases when key/encryption is required.

Adding this two, for example fixes problem with sse with customer keys.

           sse_customer_key: options[:sse_customer_key],
           sse_customer_algorithm: options[:sse_customer_algorithm]

Thanks for the report, will reproduce and investigate.

Thanks for reporting the issue. I've put together a fix that will work for the SSE CPK options and any other future options by inspecting the API model for S3 to know what options the call accepts. I've also added an integration test to ensure this continues to work.

Nice, thank you for fixing.
