Class PemReader (1.45.3)

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.
