Java – Certificate chain not found, but keystore contains private key

I’m trying to sign my apk so that I can release my app update with the following command: jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore myrelease-key.keystore CordovaApprelease unsigned.apk alias_ name But you get this error:

jarsigner: Certificate chain not found for: ¡sigalg.  ¡sigalg must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

I

just moved to a new computer, so I copied my .keystore file onto it. When I do keytool -list -v, it seems to contain the private key, so I don’t understand what’s wrong. Is the public key lost?

Apparently this is a coding issue. The command contains characters that look like a minus sign (ASCII code 0x2D), but are actually one of many dashes or hyphens (http://en.wikipedia.org/wiki/Dash).

Due to the wrong character code, the first parameter “-verbose” is recognized by jarsigner as a jar file and “-sigalg name instead of an option” is recognized as an alias:

Usage: jarsigner [options] jar-file alias

This explains why the alias in the error message is “¡sigalg” instead of the actual alias of the command, and contains an inverted exclamation mark at the beginning (previously “-” in another character set).
