public final class PemReader
Beta
PEM file reader.
Supports reading any PEM stream that contains Base64 encoded content stored inside
"-----BEGIN ...-----"
and "-----END ...-----"
tags. Each call to #readNextSection() parses the next section in the PEM file. If you need a section of a certain
title use #readNextSection(String), for example readNextSection("PRIVATE KEY")
.
To ensure that the stream is closed properly, call #close() in a finally block.
As a convenience, use #readFirstSectionAndClose(Reader) or #readFirstSectionAndClose(Reader, String) for the common case of only a single section in a PEM file (or only a single section of a given title).
Limitations:
- Assumes the PEM file section content is not encrypted and cannot handle the case of any headers inside the BEGIN and END tag.
- It also ignores any attributes associated with any PEM file section.
