I got the following error:

<Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message><Key>

The problem was that my implementation of echo did not accept -en as arguments and instead printed them. My solution was to use bash, whose echo-implementation supports -en. To do this, just replace sh in the first line with bash. If you don't want/can't use bash, the better solution would be to switch from echo to printf
