Encryption options for AWS Signing in Salesforce
Below is code snippet of C# for getting signed key for authentication to AWS:
static byte[] HmacSHA256(String data, byte[] key)
{
String algorithm = "HmacSHA256";
KeyedHashAlgorithm kha = KeyedHashAlgorithm.Create(algorithm);
kha.Key = key;
return kha.ComputeHash(Encoding.UTF8.GetBytes(data));
}
static byte[] getSignatureKey(String key, String dateStamp, String regionName, String serviceName)
{
byte[] kSecret = Encoding.UTF8.GetBytes(("AWS4" + key).ToCharArray());
byte[] kDate = HmacSHA256(dateStamp, kSecret);
byte[] kRegion = HmacSHA256(regionName, kDate);
byte[] kService = HmacSHA256(serviceName, kRegion);
byte[] kSigning = HmacSHA256("aws4_request", kService);
return kSigning;
}
Could someone please provide corresponding code in Salesforce using SFDC Security class like Crypto etc ?
The signed key needs to be the same be it run via the .Net C# code or the SFDC Code.
Thanks !
