i am trying to include login with facebook feature in flutter application. Going through the steps, i did generated key hash for debug mode. However, i'm not being able to figure out what to replace the above two values in keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64 for generating release key hash. What should i do?
You may find these info in the file: android/key.properties
Release key alias is any alias you want, remember that as you'll need them for updates. Path is the path where you want the key to be generated.

I was using keystore explorer tool to create a server crt and a private key file from my PKCS12 keystore file. The tools is great.
Is there any corresponding keytool commandline equivalent?
NO. keytool has no operations either to write out a privatekey alone from a keystore or read in a privatekey alone to a keystore. This is why we get hundreds of questions about the latter, mostly on other Stacks where they are on-topic. For the most recent one I answered, see How to resolve : jno_key_entry
For a PKCS12 keystore, openssl pkcs12 -in file -nocerts will extract the privatekey, or privatekeys, in PEM format. By default it/they is/are encrypted and you must give a (new) password, but you can use -nodes to get it/them unencrypted. If there is more than one privatekey in the keystore, you may need to edit the output to select the desired one (or ones).
For other type keystore, use keytool -importkeystore to convert to PKCS12, then continue as above. If (any type) keystore has multiple entries, you can use keytool -importkeystore with -alias to select only the desired entry, and thus not need the editing step above.
I am getting this error when trying to login with facebook.
The key hash does not match any stored key hashes.
I faced this similar error before but usually when this error appear, the facebook itself will show the key hash and what I do is just copy the key hash and register it in my facebook app. But the situation now is different because when I get the error above, I did not receive any key hash so I have no idea how to re-generate the key hash.
What I know is, you cannot use the command to re-generate another key hash for the second time like in the following code below.
keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64
For additional information just in case if this is related, the app is previously developed and the first key hash generated from other device. I copied the project and use another laptop to do the debugging. Just a guess, maybe this is one of the reason why the facebook app isn't showing the mismatch key hash?
You can still generate the key hash with the command
keytool -exportcert -alias androiddebugkey -keystore "your-release-key-path" | "your-openssl-path" sha1 -binary |"your-openssl-path" base64

I can't get my app to allow Facebook login. Everytime the users tries to login to Facebook and authenticate my app with their FB, it gives this error
Invalid key hash. They key hash xxxxxxxxxx= does not match any stored key hashes. configure your app key hashes at http://developers.facebook.com/apps/xxxxxxxx
I've already tried creating a new key hash through the OpenSSL tool like so:
keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%.android\debug.keystore | openssl sha1 -binary | openssl base64
I am facing this issue since 3 days and no result so for ,can some one help me please
Following steps solved my problem
Go to facebook account inside settings > Apps and Websites > Logged in with Facebook > Active > click on ur app > And Remove App 2: After doing that try to login now and this time you will get facebook error code 1349195 : something like go to facebook docs/android page and do the setting 3:Now run the command from yours teminal
keytool -list -printcert -jarfile yourapkname.apk
Copy the SHA1 value and convert that into base64 and paste that base64 value into you facebook account and then try login.
I followed How to create Android Facebook Key Hash? keytool -exportcert -alias androiddebugkey -keystore debug.keystore | openssl sha1 -binary | openssl base64 and the result matches what is on my facebook app settings page I still got the same error
I was trying it recently. And I used android platform.
I found there are two key hashes I have to find out.
The key hash at my build environment saved at /.android/ like you did.
The key hash from the device, which mentioned in this link( the reply of "you can use code below to get the Hash key" ).
Key hash for Facebook Android SDK
I filled them both at facebook app setting. I hope this helps you.
I am a newbie to java security and know pretty much nothing about it. I have an existing jar that was given to me couple of years which was digitally signed. However, that signature is now expired and I need to sign it again. The client has bought an X.509 certificate from Comodo and Comodo gave him the following 4 files.
1) AddTrustExternalCARoot.crt
2) COMODOCodeSigningCA2.crt
3) UTNAddTrustObject_CA.crt
4) "application_specific_key".crt
I would like to know what the next steps are in order to sign the jar file I have. I have tried doing the following things but I keep getting an error when I use jarsigner to sign the applet jar
1) keytool -import -alias AddTrustExternalCARoot -keystore altis.keystore -file AddTrustExternalCARoot.crt
2) keytool -import -alias COMODOCodeSigningCA2 -keystore altis.keystore -file COMODOCodeSigningCA2.crt
3)keytool -import -alias UTNAddTrustObject_CA -keystore altis.keystore -file UTNAddTrustObject_CA.crt
4)keytool -import -alias "application_specific_alias" -keystore altis.keystore -file "application_specific_alias".crt
5) jarsigner "application_jar_file" "application_specific_alias"
jarsigner: Certificate chain not found for: "application_specific_alias". "application_specific_alias" must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.
What am I missing?
You need to have the certificate along with the private key in a PKCS12 format.
To get this file you need to follow the link that COMODO provided via e-mail using the SAME COMPUTER and the SAME BROWSER that you used to place the order in the first place.
The certificate will be installed using your browser and you'll be able to export it in the PKCS12 format.
To export the certificate COMODO provides the following guides:
Internet Explorer / Chrome browsers:

After you have exported the certificate along with the private key in the PKCS12 format you should sign the JAVA applet using the following guide:
https://support.comodo.com/index.php?/Default/Knowledgebase/Article/View/531/0/signing-jar-files
If your .jar file already have a certificate, you can open it in a compression utility and remove the content from the META-INF folder. Then you can sign the applet.
