I would use VARCHAR for variable length data, but not with fixed length data. Because a SHA-1 value is always 160 bit long, the VARCHAR would just waste an additional byte for the length of the fixed-length field. And I also wouldn’t store the value the SHA1 is returning. Because it uses just 4 bit … Read more
You don’t need andorid for this. You can just do it in simple java. Have you tried a simple java example and see if this returns the right sha1. import java.io.UnsupportedEncodingException; import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; public class AeSimpleSHA1 { private static String convertToHex(byte[] data) { StringBuilder buf = new StringBuilder(); for (byte b : data) … Read more
Git prefixes the object with “blob “, followed by the length (as a human-readable integer), followed by a NUL character $ echo -e ‘blob 14\0Hello, World!’ | shasum 8ab686eafeb1f44702738c8b0f24f2567c36da6d Source: http://alblue.bandlem.com/2011/08/git-tip-of-week-objects.html
Neither. You should use bcrypt. The hashes you mention are all optimized to be quick and easy on hardware, and so cracking them share the same qualities. If you have no other choice, at least be sure to use a long salt and re-hash multiple times. Using bcrypt in PHP 5.5+ PHP 5.5 offers new … Read more
UPDATE You can use Apache Commons Codec (version 1.7+) to do this job for you. DigestUtils.sha1Hex(stringToConvertToSHexRepresentation) Thanks to @Jon Onstott for this suggestion. Old Answer Convert your Byte Array to Hex String. Real’s How To tells you how. return byteArrayToHexString(md.digest(convertme)) and (copied from Real’s How To) public static String byteArrayToHexString(byte[] b) { String result = … Read more
Here’s a module for calculating SHA1 hashes that is usable for Excel formulas eg. ‘=SHA1HASH(“test”)’. To use it, make a new module called ‘module_sha1’ and copy and paste it all in. This is based on some VBA code from http://vb.wikia.com/wiki/SHA-1.bas, with changes to support passing it a string, and executable from formulas in Excel cells. … Read more
Picking atoms on 10 Moons An SHA-1 hash is a 40 hex character string… that’s 4 bits per character times 40… 160 bits. Now we know 10 bits is approximately 1000 (1024 to be exact) meaning that there are 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 … Read more

Your Objective-C code (using a NSString category) can be directly translated to Swift (using a String extension). First you have to create a “bridging header” and add #import <CommonCrypto/CommonCrypto.h> Then: extension String { func sha1() -> String { let data = self.dataUsingEncoding(NSUTF8StringEncoding)! var digest = [UInt8](count:Int(CC_SHA1_DIGEST_LENGTH), repeatedValue: 0) CC_SHA1(data.bytes, CC_LONG(data.length), &digest) let output = NSMutableString(capacity: … Read more
