php - how to decode binary string from certificate -


here code works fine , can parse data certificate. however, 1 of array key's seems have binary encoded value, how can go parsing it?

openssl 1.0.1 doesn't seem convert extensions asn.1 encoding readable text.

upgrade 1.0.2 fix problem , ct_precert_scts have 1.3.6.1.4.1.11129.2.4.2.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
