Farah Juma commented on ELY-618:
--------------------------------
[~ivassile] Thanks for catching this, it's a bug. As you pointed out, the ASN1 tags
that are currently being used are single octet but we'll want to allow high tag
numbers for things like {{startExplicit}} and {{encodeImplicit}}. I think we'll want
to try to tweak {{DEREncoder}} to be able to handle the high-tag-number form.
Dead code in DEREncoder
-----------------------
Key: ELY-618
URL: https://issues.jboss.org/browse/ELY-618
Project: WildFly Elytron
Issue Type: Bug
Affects Versions: 1.1.0.Beta7
Reporter: Ondrej Lukas
Assignee: Ilia Vassilev
Labels: static_analysis
There is an unintentional dead code in writeTag method of
org.wildfly.security.asn1.DEREncoder. Variable {{tagNumber}} can be assigned to 31 as its
maximal value from {{int tagNumber = tag & TAG_NUMBER_MASK;}} (because
{{TAG_NUMBER_MASK = 0x1f}}) on line 576 [1] which means that condition {{if (tagNumber
< 128)}} on line 582 is always true. It causes that else branch is never executed.
