SHA1 Hash Results

Question

I am trying to encryption a string using SHA1 encryption. Test string

The quick brown fox jumps over the lazy dog

2fd4e1c67a2d28fced849ee1bb76e7391b93eb12 (encryption token)

You can validate this here http://www.sha1-online.com/

But if I use same string in Salesforce with this code

blob hashSHA1 =Crypto.generateDigest('SHA1', blob.valueOf('The quick brown fox jumps over the lazy dog'));
String hashBase64SHA1 = EncodingUtil.base64encode (hashSHA1);
System.debug (hashBase64SHA1);

Then I get the output

If anyone can let me know what I am doing wrong here or if I need to update anything or the correct method that would be helpful.

One is hex, the other is base64 encoded. If you didn't want base64 encoded output, why did you call the base64encode function? — David Schwartz, Aug 17 '16 at 08:32

You Should use this

String shasign = EncodingUtil.convertToHex(Crypto.generateDigest('SHA1',Blob.valueOf(Your String)));

Clarification -:
base64Encode will simply convert a Blob to an unencoded String representing its normal form. It will not encode the blob in any form just simply return the String.

Whereas
convertToHex will return a hexadecimal (base 16) representation of the inputBlob.

This is correct. To clarify you could maybe add a small description of the difference between base64encode() and convertToHex(). – user254875486 Aug 17 '16 at 08:26
