extractKeyPairs
public Collection<KeyPair> extractKeyPairs(SessionContext session, NamedResource resourceKey, String beginMarker, String endMarker, FilePasswordProvider passwordProvider, InputStream stream, Map<String,String> headers) throws IOException, GeneralSecurityException
- Specified by:
extractKeyPairs
in classAbstractKeyPairResourceParser
- Parameters:
session
- TheSessionContext
for invoking this load command - may benull
if not invoked within a session context (e.g., offline tool or session unknown).resourceKey
- A hint as to the origin of the text linesbeginMarker
- The line containing the begin markerendMarker
- The line containing the end markerpasswordProvider
- TheFilePasswordProvider
to use in case the data is encrypted - may benull
if no encryptedstream
- The decoded dataInputStream
headers
- Any headers that may have been available when data was read- Returns:
- The extracted
KeyPair
s - may benull
/empty if none. - Throws:
IOException
- If failed to parse the dataGeneralSecurityException
- If failed to generate the keys
-
decodeDSSKeyPair
public static KeyPair decodeDSSKeyPair(KeyFactory kf, InputStream s, boolean okToClose) throws IOException, GeneralSecurityException
The ASN.1 syntax for the private key:
DSAPrivateKey ::= SEQUENCE { version Version, p INTEGER, q INTEGER, g INTEGER, y INTEGER, x INTEGER }
- Parameters:
kf
- TheKeyFactory
To use to generate the keyss
- TheInputStream
containing the encoded bytesokToClose
-true
if the method may close the input stream regardless of success or failure- Returns:
- The recovered
KeyPair
- Throws:
IOException
- If failed to read or decode the bytesGeneralSecurityException
- If failed to generate the keys
