OpenSSL4JProvider

public OpenSSL4JProvider()

Constructor for the JCA Provider for OpenSSL JNI.

Throws:

IllegalStateException - if the native object file can't be loaded and the class can't be used.

Method Details

getLibraryVersion

private static double getLibraryVersion()

getNames

private static Map<String,String> getNames(Set<String> availableOpenSslAlgorithmNames)

Gets the names and the aliases of all message digest algorithms.

Returns:

a map mapping from algorithm name / alias to algorithm class.

createAliases

private static Map<String,String> createAliases(Map<String,String> map)

Creates some aliases for an input map.

Parameters:

map - a map with keys being algorithm names of the form "MessageDigest.MD5" and the keys being java class names.

Returns:

a map mapping from algorithm name / alias to algorithm class.

getOpenSSLHashnames

private static Map<String,String> getOpenSSLHashnames(Set<String> availableOpenSslAlgos)

Fills a map with the names of all algorithms in OpenSSL-JNA.

Returns:

mapping from algorithm name to class name.
