Android 4.0 or later has supported amanagement for'Trusted Root CA Certificate' store by settings(See 'settings > security > trusted CA certificate').However its certificate viewer shows just onlyfollowing information.- Subject Name- Issuer Name- Validity Period (missing hours,mins,seconds)- SHA256 finger print- SHA1 finger printThis 'Root CA Viewer Lite' showsmuch more information as following:- X.509 Certificate Basic Fields- Version- Serial Number- Issuer Name- Validity Period (with hours,mins,seconds in local time)- Subject Name- Subject Public Key Info- Public Key of RSA/DSA, key size- Signature Algorithm- X.509v3 extensions (with critical flags)- Basic Constraints (cA flag, pathLen)- Key Usage- Extended Key Usage- Issuer Alt Name- Subject Alt Name- Other Information- SHA256 finger print- SHA1 finger print- Key Store Alias NameSUPPORTED VERSION:Android 4.0 or later.Since trusted root certificate store architecturewas changed by Android 4.0.If you need CA viewer for old Android,'CACertMan' or otherscan be recommended.From the version 1.2.2, this can export a zip archive ofDER formatted X.509 trusted root certificates to /sdcardfolder.NOTE:** Permission for 'INTERNET' and 'ACCESS_NETWORK_STATE'arerequired to show Ads.

What cryptographic algorithms can be used onyour Android?Cryptographic functionality of Android depends onJava Cryptographic Extension(JCE) architecture.This 'JCE Provider Checker' shows a list of their algorithmsandmay be useful for application developer.FEATURES:* Show categolized supported algorithm list in a ListView.Its categories are following:- Cipher- MessageDigest- Signature- Mac(Message Authentication)- SecureRandom- KeyAgreement- KeyFactory- KeyGenerator- KeyPairGenerator- SSLContext- KeyStore- CertificateFactory- CertStore- CertPathBuilder- CertPathValidator* Show algorithm list in a Text Edit andit can be sent to your Email address.SUPPORTED VERSION:Android 3.0 or later.NOTE:** Permission for 'INTERNET' and 'ACCESS_NETWORK_STATE'arerequired for some Ads.
