Step1:SetupOSenvironment

AndroidisusingaspecifickeystonetypecalledBouncycastleKeyStore(BKS).

IdownloadthejarpackageandplaceitinmyJAVA_HOMElibdirectory

http://www.bouncycastle.org/archive/141/bcprov-jdk16-141.jar

OnmyMAClaptop,thedirectoryishere:

/System/Library/Frameworks/JavaVM.framework/Home/lib/ext

>cd/System/Library/Frameworks/JavaVM.framework/Home/lib/ext

>sudocp/Users/carl/data/bcprov-jdk16-141.jar./

TrytomanuallyinstalltheCERT

>adbpull/system/etc/security/cacerts.bks/Users/carl/data/

PreparetheCERTfile,opentheURLwithFirefox.

[AddException…]--->[View]--->[Details]---->[Export]---->Filenamesillycatwith[X.509Certificate(PEM)]

>cd/Users/carl/data

>mvsillycatsillycat.cert

Checkthecertificatefile

>keytool-printcert-filesillycat.cer

Example:

keytool-keystorecacerts.bks-storetypeBKS-providerorg.bouncycastle.jce.provider.BouncyCastleProvider-storepasschangeit-importcert-trustcacerts-aliassomealias-fileca.cer-noprompt

>keytool-keystorecacerts.bks-storetypeBKS-providerorg.bouncycastle.jce.provider.BouncyCastleProvider-storepasschangeit-importcert-trustcacerts-aliassillycat-filesillycat.cer-noprompt

IusedtothinkthatIdonothavepassword,soIgetridoftheline-storepasschangeit,Igot

PushthechangedfiletoAVD

>adbpushcacerts.bks/system/etc/security/cacerts.bks

Maybe,thatbecauseIgettheCERfilebywrongway.

>echo|openssls_client-connectapi.local.sillycat.com:4432>&1|sed-ne'/-BEGINCERTIFICATE-/,/-ENDCERTIFICATE-/p'>s1.pem

ImportthePEMfileagain

>keytool-keystorecacerts.bks-storetypeBKS-providerorg.bouncycastle.jce.provider.BouncyCastleProvider-storepasschangeit-importcert-trustcacerts-aliass1-files1.pem-noprompt

Pushthefileagain
