From the AWS forum :
Derive your signing key. To do this, use your secret access key to create a series of hash-based message authentication codes (HMACs). This is shown in the following pseudocode, where HMAC(key, data) represents an HMAC-SHA256 function that returns output in binary format. The result of each hash function becomes input for the next one.
I've no idea how to create HMAC-SHA256 code from my AWS secret key.
I want to use assetlinks.json for appindexing.I am supposed to use an SHA256 fingerprint, but when I print out the signingReport in Android Studio, I only have SHA1.Can I use SHA1, if not, how can I get an SHA256 signed app?
Using Manish Jain's answer I have managed to list only the debug keys, which is more than I could do by myself, but if I put my actual keystore path and jks file in the path, "keytool -list -v -keystore "C:\Users\myself\Keystores\android.jks" -alias mykey -storepass 1password -keypass 2password" a different set of keys come up, which I assume would be the release key set.
The BIG QUESTION is why android studio only lists the debug keys when I print out the signingReport from Gradle and why it says "Variant: releaseUnitTest, Config: none"? Any idea?
By the way, this question has nothing to do with the suggested duplicate.
EDIT:Replying to a question from jyomin 2.I hope it helps others too.
***** For Release:1, go to: C:\Program Files\Java\jdk1.7.0_25\bin (or wherever your jdk file is)2, type "cmd" in address bar in win explorer3, add: keytool -list -v -keystore "C:\Users\yourUserName\Keystores\android.jks" -alias yourAppName -storepass yourPasswordToKeystore -keypass yourPasswordToRequiredAppKey
Be careful!!!If you have multiple keys in the keystore, it might not give you the correct matching one to the given app!!!
Another way of getting the SHA256 for your app:Either on the Developer Console or Firebase you can find the related SHA256 key somewhere. I couldn't find it now, but if you keep looking, it is there somewhere.
I just found it on Google Play Developer Console:
It will show you the SHA keys
I need the scratch algorithm or code in vb.net for SHA-1 (Secure Hash Algorithm)I know there is a built in Class "SHA1CryptoServiceProvider" and a built in method "sha.ComputeHash()"But can anyone give me the scratch?TIA
I am running into a problem with verifying a SHA256 hash signature generated using OpenSSL.
When I invoke
openssl dgst -sha256 -binary -out hash.sha256 in_file
and I (xxd -g 1 hash.sha256), it looks like this -
00000000: d7 e6 1b 81 5c 32 28 30 7b 7b 45 e1 ef 40 6b 93 00000010: 34 67 d0 a4 ee c0 64 d1 20 e7 c1 c3 a9 f2 a9 a9
Similarly, when I invoke
openssl dgst -sha256 -out hash.sha256 -sign private.pem in_file
to hash and sign all at once, and subsequently verify using
openssl rsautl -in hash.sha256 -out hash.verified -inkey private.pem -verify
and (xxd -g 1 hash.verified), (which should be the same as hash.sha256 from above, I believe) I see
00000000: 30 31 30 0d 06 09 60 86 48 01 65 03 04 02 01 05 00000010: 00 04 20 d7 e6 1b 81 5c 32 28 30 7b 7b 45 e1 ef 00000020: 40 6b 93 34 67 d0 a4 ee c0 64 d1 20 e7 c1 c3 a9 00000030: f2 a9 a9
If you look closely, it appears that hash.verified has 19 bytes of data prepended to it, followed by the correct hash (or at least the same as hash.sha256 from above).
What is it putting in my hash?
My quetion is simple, here's a JSON :
This JSON is received by an App that rejects it if you change the slightest part of it.
This App is probably or obviously able to check the integrity of the JSON thanks to hash at the end : 80db826a05000d6b4ce056483813e722d3ab54e6
Can you find what hash is used ?
I tried MD5 ans SHA1 but i never get back the same hash, maybe i'am doing it wrong ?
