Use JDK version 1.6 instead of 1.7 because 1.7 generates the fingerprint with SHA1 by default. or you can use (-v) option of the keytool to give you all supported algorithms output and you will find the MD5 in it. for examble : keytool -v -list -keystore [your keystore path] and then enter the password … Read more
It’s an old question but one thing needs some clarification: This question and the answers below talk about the Git hash of a file which is not exactly the same as “the SHA1 of this file” as asked in the question. In short: If you want to get the Git hash of the file in … Read more
What about: import java.security.MessageDigest; import java.security.NoSuchAlgorithmException; import java.util.Formatter; public static String SHAsum(byte[] convertme) throws NoSuchAlgorithmException{ MessageDigest md = MessageDigest.getInstance(“SHA-1”); return byteArray2Hex(md.digest(convertme)); } private static String byteArray2Hex(final byte[] hash) { Formatter formatter = new Formatter(); for (byte b : hash) { formatter.format(“%02x”, b); } return formatter.toString(); }
Pseudocodish: def sign_request(): from hashlib import sha1 import hmac # key = b”CONSUMER_SECRET&” #If you dont have a token yet key = b”CONSUMER_SECRET&TOKEN_SECRET” # The Base String as specified here: raw = b”BASE_STRING” # as specified by OAuth hashed = hmac.new(key, raw, sha1) # The signature return hashed.digest().encode(“base64”).rstrip(‘\n’) Signature errors usually reside in the base-string, … Read more
DEBUG: Click on the Gradle tab on the right hand side of the view. Go to the ROOT folder -> Tasks -> android -> signingReport Double click, this will build with the signingReport and post in your bottom view your SHA1. RELEASE: In android studio. Build -> Generate Signed APK… and click Next Copy your … Read more
On your PHP side, use single-quotes around the key so that the $ character is not treated as a variable reference. i.e., hash_hmac(“sha1”, “helloworld”, ‘PRIE7$oG2uS-Yf17kEnUEpi5hvW/#AFo’) Otherwise, the key you really get is PRIE7-Yf17kEnUEpi5hvW/#AFo (assuming the variable $oG2uS is not defined).
You see a difference because git hash-object doesn’t just take a hash of the bytes in the file – it prepends the string “blob ” followed by the file size and a NUL to the file’s contents before hashing. There are more details in this other answer on Stack Overflow: How to assign a Git … Read more
I suggest you have a look to this SO page, CRC vs MD5/SHA1. Speed and collisions are discussed in this other thread. And as always Wikipedia is your friend. If I had to choose, there is an important question to answer: do you want that in any case there is no collision – or, at … Read more
Here’s how you generate an HMAC using SHA-256: NSString *key; NSString *data; const char *cKey = [key cStringUsingEncoding:NSASCIIStringEncoding]; const char *cData = [data cStringUsingEncoding:NSASCIIStringEncoding]; unsigned char cHMAC[CC_SHA256_DIGEST_LENGTH]; CCHmac(kCCHmacAlgSHA256, cKey, strlen(cKey), cData, strlen(cData), cHMAC); NSData *HMAC = [[NSData alloc] initWithBytes:cHMAC length:sizeof(cHMAC)]; NSString *hash = [HMAC base64Encoding]; I’m not aware of an HOTP library, but the algorithm … Read more
using (FileStream fs = new FileStream(@”C:\file\location”, FileMode.Open)) using (BufferedStream bs = new BufferedStream(fs)) { using (SHA1Managed sha1 = new SHA1Managed()) { byte[] hash = sha1.ComputeHash(bs); StringBuilder formatted = new StringBuilder(2 * hash.Length); foreach (byte b in hash) { formatted.AppendFormat(“{0:X2}”, b); } } } formatted contains the string representation of the SHA-1 hash. Also, by using … Read more
