openssl: checking out RSA private key files in .rsa and .pem format

Posted by jpluimers on 2019/03/19

While checking out an issue with the SSH server for ContinuaCI issue (see info below), I wanted to look at the files leading to the issue: .pem and .rsa files with the private key for the SSH server.

So I browsed through my series of openssl related articles to see if I already had made a script better explaining the cryptic openssl command-line parameters. I didn’t have it yet, but it turned out to be really simple:

C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.rsa
writing RSA key
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.rsa -text
Private-Key: (1024 bit)
modulus:
    ..:..:..:.....
publicExponent: 35 (0x23)
privateExponent:
    ..:..:..:.....
prime1:
    ..:..:..:.....
prime2:
    ..:..:..:.....
exponent1:
    ..:..:..:.....
exponent2:
    ..:..:..:.....
coefficient:
    ..:..:..:.....
writing RSA key
-----BEGIN RSA PRIVATE KEY-----
...
-----END RSA PRIVATE KEY-----
C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.pem
Enter pass phrase for server_keypair.pem:
unable to load Private Key
2675996:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:529:
2675996:error:23077074:PKCS12 routines:PKCS12_pbe_crypt:pkcs12 cipherfinal error:p12_decr.c:108:
2675996:error:2306A075:PKCS12 routines:PKCS12_item_decrypt_d2i:pkcs12 pbe crypt error:p12_decr.c:139:
2675996:error:0907B00D:PEM routines:PEM_READ_BIO_PRIVATEKEY:ASN1 lib:pem_pkey.c:141:
C:\ProgramData\VSoft\ContinuaCI\SSHD>"C:\Program Files (x86)\Git\usr\bin\openssl.exe" rsa -in server_keypair.pem -passin pass:password
unable to load Private Key
2675996:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:529:
2675996:error:23077074:PKCS12 routines:PKCS12_pbe_crypt:pkcs12 cipherfinal error:p12_decr.c:108:
2675996:error:2306A075:PKCS12 routines:PKCS12_item_decrypt_d2i:pkcs12 pbe crypt error:p12_decr.c:139:
2675996:error:0907B00D:PEM routines:PEM_READ_BIO_PRIVATEKEY:ASN1 lib:pem_pkey.c:141:

The command-lines use the [WayBack]rsa tool with:

  • the -in parameter
  • (for the first file) the -text parameter to dump it into human readable form
  • (for the second file) the -passin parameter with a [WayBack] pass phrase argument pass:password.

The server_keypair.pem file (having the header -----BEGIN ENCRYPTED PRIVATE KEY----- and footer -----END ENCRYPTED PRIVATE KEY-----) was a password protected RSA private key where somehow ContinuaCI had the wrong password for.

I’m not sure it’s a good idea that the server_keypair.pem file has not password at all.

Version 1.8.1 History – builds 121-185 – Continua CI

Posted by jpluimers on 2016/12/07

I’ve been very busy with broken hardware and operating systems lately so today was the first chance to post about recent Version 1.8.1 History of  Continua CI. During October and November the below builds got released.

For almost all of them, you will need to update your agents after installing the build.

v1.8.1.185, November 23rd, 2016

Changes

  • Update: Added preliminary support for Visual Studio 2017 RC to MSBuild, VSTest, MSTest and Visual Studio actions
  • Fix: Issue where ExecuteRepositoryServerSideScripts app setting was not being read preventing running of Git post commit scripts.

v1.8.1.178, November 22nd, 2016

Changes

  • Fix: “changeset.style” file was missing from installer causing error when getting new changesets for new Mercurial repositories.
  • Fix: Issue where Shared Resource Locks at the configuration level would be released before the end of the build, if Shared Resource Locks existed at the stage level and were released.
  • Fix: Build version is now truncated to fit into the maximum field length of 128 characters.
  • Update: Email publisher now supports wider range of secure sockets options. This also fixes an issue where you it would always try to use TLS if it was supported by the server.

v1.8.1.167, November 15th, 2016

Changes

  • Fix: Issue where enabling a configuration would cause all time triggers in other configurations to stop working.
  • Update: Any updates to loggers in the Continua CI Server service configuration file, such as enabling debug logging, are no longer reset when running the installer.

v1.8.1.165, November 14th, 2016

Changes

  • Fix: Repository error status was being reset to “Ready” status when getting new changesets.
  • Fix: Associated triggers are now updated to point to the new repository when repository edit requires it to be recreated.
  • Fix: Concurrency issue with build event handlers causing incorrect build data to be used.
  • Update: Bundled Mercurial used for repository cache has been upgraded to version 3.9.2
  • Update: Improvements to speed when exporting files from agent repository cache to agent workspace.
  • Update: Agent installer has been updated to allow it to be run silently and take additional command line parameters. The relevant parameters are:
    • /usage (optional) – shows usage information.
    • /silent (optional) – runs the setup in silent mode. Note that progress bars will still be displayed.
    • /verysilent (optional) – runs the setup in completely silent mode. No UI is displayed.
    • /log=”filename” (optional) – creates a log file with the specified filename.
    • /dir=”x:\dirname” (optional) – overrides the default installation directory name.
    • /serviceUser (required in silent modes) – the domain and user name of the service user e.g. domain\username.
    • /servicePassword (required in silent modes) – the password of the service user.
    • /serverHostName (optional) – the host name of the ContinuaCI service. Defaults to “localhost” if not provided.
    • /serverPort (optional) – the port of the ContinuaCI service. Defaults to 9000 if not provided.
    • /agentPort (optional) – a port for the agent being installed. Defaults to 9002 if not provided.
    • /workspacePath (optional) – the local path to the agent workspace folder. Defaults to “C:\CI_AWS” if not provided.
  • Update: Now showing the finished time for the last finished build rather than Never for the last queued/running build on List View dashboard.
  • Update: JUnit parser now includes test case times.
  • Update: Diagnostics report is now generated in the background to prevent timeouts.
  • Update: Further improvements to build queue performance.

v1.8.1.121, October 11th, 2016

Changes

  • Fix: Regression bug in v1.8.1.118 where Path Exists property collector plugin would always return false.

Continua CI v1.8.1.118 released

Posted by jpluimers on 2016/10/11

Source: Version 1.8.1 History | Continua CI – v1.8.1.118

v1.8.1.118

October 10th, 2016

Changes

  • Update: Reduced CPU usage on server when using a large number of time triggers.
  • Update: Reduced wait time between time triggers running simultaneously.
  • Update: Reduced CPU usage and throughput of stage queue.
  • Update: The >> operator is now implemented in repository rules. This is used to clean the destination folder before copying files. It is useful when a stage can run on the same agent as a previous stage as the agent workspace is not automatically cleared between stages.
    Note: We have also changed the default workspace and repository rules so that the >> operator is used for any server to agent rules in new stages. This is to ensure that the workspace is always cleared and are no surprises dependent on the agent the stage runs on. This can be changed to a single > to use the previous behaviour.
  • Update: Environment variables now expanded in all path type property collectors. This will for example allow you to use %HOME% to define the path to check when using a Path Access PlugIn property collector.
  • Update: Added descriptions and help information to property collector dialog fields.
  • Update: Queued stages are now prevented from starting in the few seconds after an agent has gone offline.
  • Fix: Issue where changes to user group membership were not picked up for several minutes unless the service was restarted.
  • Fix: Triggers were not being monitored after a disabled configuration was re-enabled.
  • Fix: Issue where agents with unlimited concurrent stages would not be selected to run stage.
