New Features

Change Description
AWS::S3 Streaming Uploads and Downloads AWS::S3::S3Object#write and #read can now both stream object data.
s3 =
obj = s3.buckets['my-bucket'].objects['key']

# upload a file to s3 in chunks

# download a file in chunks'output.txt', 'w') do |file| do |chunk|
AWS::S3 Client-Side Encryption You can now encrypt your data locally before uploading to Amazon S3. To do this you need to provide an encryption key.
require 'openssl'
s3 =
obj = s3.buckets['my-bucket'].objects['key']

# generate a key
key =

# upload data, encrypting it first
obj.write('Hello World!', :encryption_key => key)

# read without the encryption key returns the encrypted data
#=> "\xE6)\x8B9K/j\x9D\xACK\x8Et\xEEf\x1CQ"

# download and decrypt the data => key)
#=> 'Hello World!'
