Has anyone had any success in accessing AWS S3 path-style request (https:<amazon domain>/<path>) using Authorization (Access Key and Secret Access Key)?

I checked S3 documentation and bump into this: docs.aws.amazon.com/.../RESTAuthentication.html
Authorization = "AWS" + " " + AWSAccessKeyId + ":" + Signature;
Signature = Base64( HMAC-SHA1( YourSecretAccessKeyID, UTF-8-Encoding-Of( StringToSign ) ) );
StringToSign = HTTP-Verb + "\
" +
          Content-MD5 + "\
" +
          Content-Type + "\
" +
          Date + "\
" +
          CanonicalizedAmzHeaders +
          CanonicalizedResource;

I'm looking for HMAC Sha-1 in the available functions in Cryptography functions to generate the SIGNATURE as stated above but to no success. Please advise.

I did this with the following code -

calculaterfc2104hmac(
ri!verb & char(
10
) & if(
isnull(
ri!content
),
"",
md5hash(
ri!content
)
) & char(
10
) & ri!contentType & char(
10
) & char(
10
) & if(
isnull(
ri!canonicalHeaders
),
"",
ri!canonicalHeaders & char(
10
)
) & "x-amz-date:" & ri!timestamp & char(
10
) & ri!resource,
cons!COMMON_AWS_SECRET_ACCESS_KEY
)

calculaterfc2104hmac is a custom function we wrote.....you can write your own plugin to calculate the hmac.
