Bug 3493

Summary: PGP/MIME signature uses uppercase micalg parameter value
Product: Claws Mail (GTK 2) Reporter: Bodo Graumann <mail>
Component: Plugins/Privacy/PGPAssignee: users
Status: RESOLVED DUPLICATE    
Severity: normal    
Priority: P3    
Version: 3.9.0   
Hardware: PC   
OS: Linux   

Description Bodo Graumann 2015-08-09 09:52:07 UTC 
When signing a mail with the PGP/MIME plugin, the parameter value of "micalg" is written as "PGP-SHA1".

According to RFC 1521, Section 2 (https://tools.ietf.org/html/rfc1521#section-2):
   [...] parameter values are case-sensitive unless otherwise specified for
   the specific parameter.

and RFC 3156, Section 5 (https://tools.ietf.org/html/rfc3156#section-5) states:
   [...] converting the text name to lower case and prefixing it with the four characters "pgp-"

while there is no mention in RFCs 1847 or 3156, that the micalg parameter is case insensitive.

So please change it to lowercase.

Try the latest release, re-open if the problem remains.

Sorry, my bad. I did not search in closed bugs.
