Hi jeff,
i am very surprise to see that why you are doing encryption with private key, can we done this, usually we done encryption with public key and do decryption with private key. Please replay to this comment

Hi Jeff,
Thanks for the blogs.

Have you ever tried to encrypte data & put that encrypted data in cookies on one page & try to encrypte that data into other page from cookies in salesforce apex class.

Hi Jeff,

Very important, the error from salesforce is misleading the third argument is not of type “string” but “Blob” so the solution is :
public class cryptotest
{
private String getMac(String RequestString, String secretkey) {
String algorithmName = ‘hmacSHA1′; //’RSA’;
Blob input = Blob.valueOf(RequestString);
Blob key = Blob.valueOf(secretkey);
Blob signing =Crypto.generateMac(algorithmName, input, key);
return EncodingUtil.urlEncode(EncodingUtil.base64Encode(signing), ‘UTF-8′);
//return ”;
}
}

@AB, check the API version of your class. I may be using an older version and you need to update to 19 or 20.

public class cryptotest
{
private String getMac(String RequestString, String secretkey) {
String algorithmName = ‘hmacSHA1′; //’RSA’;
Blob input = Blob.valueOf(RequestString);
Blob signing =Crypto.generateMac(algorithmName, input, secretkey);
return EncodingUtil.urlEncode(EncodingUtil.base64Encode(signing), ‘UTF-8′);
//return ”;
}
}

I wrote this litte class in my sandbox and I am getting a very annoying error “Error: Compile Error: Method does not exist or incorrect signature: Crypto.generateMac(String, Blob, String) at line 6 column 23
” can you help ?

Thanks
