+
+Package pkcs12 implements some of PKCS#12 (also known as P12 or PFX).
+It is intended for decoding P12/PFX files for use with the `crypto/tls`
+package, and for encoding P12/PFX files for use by legacy applications which
+do not support newer formats.  Since PKCS#12 uses weak encryption
+primitives, it SHOULD NOT be used for new applications.
+
+This package is forked from `golang.org/x/crypto/pkcs12`, which is frozen.
+The implementation is distilled from https://tools.ietf.org/html/rfc7292
+and referenced documents.
+
+This repository holds supplementary Go cryptography libraries.
