sha1

According to my requirement: The input string has to be converted into Byte Values. Each character of string , which are 16 bit values , has to be converted to low 8 bits. The Sha1 is then computed over the byte Array. The resulting SHA-1 is converted into a 40 character string. I know how to convert a string into SHA1 , but the rest of part is a bit gloomy to me. I have been able to do the last two steps. unsigned char digest[CC_SHA1_DIGEST_LENGTH]; NSData *dataString = [yourString dataUsingEncoding: NSUTF8StringEncoding]; if (CC_SHA1([dataString bytes], [dataString length], digest)) { //Sha1

I am a little bit confused. I want to get the bytes of an String, which is hashed with SHA1. JavaScript: var content = "somestring"; console.warn(content.getBytes().toString()); console.warn(CryptoJS.SHA1(content.getBytes().toString()).toString().getBytes()); String.prototype.getBytes = function () { var bytes = []; for (var i = 0; i < this.length; i++){ bytes.push(this.charCodeAt(i)); } return bytes; }; Array.prototype.toString = function(){ var result = ""; for(var i = 0; i < this.length; i++){ result += this[i].toString(); } return result; } which gives me 115111109101115116114105110103 [52

I have generated my SHA1 code from my keystore but when I try to create an OAuth client 2.0, Google game console is giving me the error: "Certificate fingerprint is invalid". Anyone knows why this happens? How do I fix this? I've contacted Google Play Developer Support about this issue (I've got a same problem). Here is their answer : Please ensure the key is set to 2048 bit and is valid for at least 25 years. I've tried it, but sadly my debug.keystore is still not getting accepted, maybe there will be some luck on your side. $ keytool -genkey -v -keystore debug.keystore -storepass android

I'm trying to hash a number, represented by hex string with Java security library. Meaning, If I have the String "AABBCCDD" I want to hash it not as this is an ascii input, which is 0x65, 0x65, 0x66, 0x66, 0x67, 0x67, 0x68, 0x68, but as four bytes - 0xAA, 0xBB, 0xCC, 0xDD. I managed to do it with low values such as "112233445566" (since bytes are signed in Java) but failed with high values. Does someone know how to implement such thing? Thanks, Binyamin gleber First convert your hex into byte[] using for example this: Convert a string representation of a hex dump to a byte array using Java?

I have a smartcard and I need to sign a file with this. That is a big problem as I see in stackover. I couldnt use RSACryptoServiceProvider, bkz it doesnt support RSA-SHA256 alogrithm. At First I used CAPICOM.dll , like code bellow, SignedData sed = new SignedData(); sed.Content = "a"; // data to sign Signer ser = new Signer(); ser.Certificate = cc; string singnn = sed.Sign(ser, false, CAPICOM_ENCODING_TYPE.CAPICOM_ENCODE_BASE64); But there isnt a public key to validate my signature value,, I couldnt get a validate key from capicom.dll. And after , I used X509Certificate2 , and
