x/crypto: Add pkcs12 package for reading pkcs12 data
Package pkcs12 provides some Go implementations of PKCS#12. This implementation is distilled from https://tools.ietf.org/html/rfc7292 and referenced documents. It is intented for decoding P12/PFX-stored certificate+key for use with the crypto/tls package. Package includes @dgryski's RC2 implementation as a sub package as requested in https://github.com/golang/go/issues/10621. Change-Id: I78401241e39cd0099e9082a3a227cf0a3a36e6d1 Reviewed-on: https://go-review.googlesource.com/11986 Reviewed-by: Adam Langley <agl@golang.org> Run-TryBot: Adam Langley <agl@golang.org>
