For me the blog is this odd mix of diary and technical notes, this time I guess the post is more of a technical note — here is a quick guide on how to generate RFC 3161 time-stamps using OpenSSL and curl.<\/p>\n
<\/p>\n
1.\u00a0Create the file you will want to timestamp<\/p>\n
<\/p>\n
copy con inputfile.txt<\/p>\n
This is my test file.<\/p>\n
^Z<\/p>\n
<\/p>\n
2. Generate a timestamp request<\/p>\n
<\/p>\n
openssl ts -query -data inputfile.txt -cert -sha256 -no_nonce -out request.tsq<\/p>\n
<\/p>\n
3. Send the request to your timestamp server<\/p>\n
<\/p>\n
curl -k -H “Content-Type: application\/timestamp-query” -H Host:timestamp.globalsign.com –data-binary @request.tsq “http:\/\/timestamp.globalsign.com”\u00a0 <\/span>>inputfile.txt.tsr<\/span><\/p>\n <\/p>\n 4. Verify the timestamp response<\/p>\n <\/p>\n openssl ts -reply -in inputfile.txt.tsr -text<\/p>\n <\/p>\n This is going to give you some output that looks something like this:<\/p>\n <\/p>\n Using configuration from C:\\OpenSSL-Win64\\bin\\openssl.cfg<\/p>\n Status info:<\/p>\n Status: Granted.<\/p>\n Status description: unspecified<\/p>\n Failure info: unspecified<\/p>\n TST info:<\/p>\n Version: 1<\/p>\n Policy OID: 1.3.6.1.4.1.4146.2.2<\/p>\n Hash Algorithm: sha256<\/p>\n Message data:<\/p>\n \u00a0\u00a0\u00a0 0000 – 58 df 63 8c 5b bf ff ca-ad 13 c9 6e 93 96 cd 25\u00a0\u00a0 X.c.[……n…%<\/p>\n \u00a0\u00a0\u00a0 0010 – 66 5e f1 eb ba 8e 7f 74-6d 65 04 3c 5d ea e4 35\u00a0\u00a0 f^…..tme.<]..5<\/p>\n Serial number: 0x2487F5EA8A5A085844ED68A8A7426E07E692E1BD<\/p>\n Time stamp: Sep 17 05:08:38 2013 GMT<\/p>\n Accuracy: unspecified<\/p>\n Ordering: no<\/p>\n Nonce: unspecified<\/p>\n TSA: DirName:\/C=SG\/O=GMO GlobalSign Pte Ltd\/CN=GlobalSign TSA for Standard – G1<\/p>\n Extensions:<\/p>\n It\u2019s that easy.<\/p>\n","protected":false},"excerpt":{"rendered":" For me the blog is this odd mix of diary and technical notes, this time I guess the post is more of a technical note — here is a quick guide on how to generate RFC 3161 time-stamps using OpenSSL and curl. 1.\u00a0Create the file you will want to timestamp copy con inputfile.txt […]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[4],"tags":[97,22,96,98],"class_list":["post-395","post","type-post","status-publish","format-standard","hentry","category-thoughts","tag-curl","tag-openssl","tag-rfc3161","tag-timestamping"],"_links":{"self":[{"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=\/wp\/v2\/posts\/395","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=395"}],"version-history":[{"count":0,"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=\/wp\/v2\/posts\/395\/revisions"}],"wp:attachment":[{"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=395"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=395"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/unmitigatedrisk.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=395"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
