Specified by:

extractKeyPairs in class AbstractKeyPairResourceParser

Parameters:

session - The SessionContext for invoking this load command - may be null if not invoked within a session context (e.g., offline tool or session unknown).

resourceKey - A hint as to the origin of the text lines

beginMarker - The line containing the begin marker

endMarker - The line containing the end marker

passwordProvider - The FilePasswordProvider to use in case the data is encrypted - may be null if no encrypted

stream - The decoded data InputStream

headers - Any headers that may have been available when data was read

Returns:

The extracted KeyPairs - may be null/empty if none.

Throws:

IOException - If failed to parse the data
