KEYS: Add parser for TPM-based keys [ver #2] For TPM based keys, the only standard seems to be described here: http://david.woodhou.se/draft-woodhouse-cert-best-practice.html#rfc.section.4.4 Quote from the relevant section: "Rather, a common form of storage for "wrapped" keys is to encode the binary TCPA_KEY structure in a single ASN.1 OCTET-STRING, and store the result in PEM format with the tag "-----BEGIN TSS KEY BLOB-----". " This patch implements the above behavior. It is assumed that the PEM encoding is stripped out by userspace and only the raw DER/BER format is provided. This is similar to how PKCS7, PKCS8 and X.509 keys are handled.
