signing cert update; re-key from godaddy

steps taken
1) generate keystore with private key

keytool -genkey -alias signing -keyalg RSA -keysize 2048 -keypass
"*snip*" -keystore signing.jks -storepass
"*snip*" -dname "CN=Selventa\, Inc,O=Selventa\,
Inc,C=US,ST=Massachusetts,L=Cambridge"

2) generate csr from keystore

keytool -certreq -v -alias signing -file signing.csr -keystore
signing.jks

3) re-key certificate on GoDaddy using SHA-1 algorithm

SHA-2 is recommended due to Windows constraints being imposed in 2017,
but GoDaddy provides another certificate in the chain for these.  That
certificate is not trusted by default in Java.

4) import certificate chain

keytool -import -trustcacerts -keystore signing.jks -storepass
"*snip*" -alias signing -file cert.pem
