Can't Get Sha-1 Fingerprint From Signature.jks

i have a huge problem: i don't know how to get the SHA-1 fingerprint from the file that i use to sign my app. Let's assume that my jks file (generated from Android Studio) is named

Solution 1:

Ok, sorry everybody, problem solved, i have typed the wrong path to my keystore file(the file with .jks extension), and after "-alias" i put the name of the apk instead the name of the alias, so the correct syntax was:

keytool -list -v -keystore C:\signature.jks -alias aliasName

Solution 2:

alias name is not mandatory. For me following worked:

keytool -keystore "C:\signature.jks" -list -v
