Examples of HexDigest

com.subgraph.orchid.data.HexDigest
This class represents both digests and fingerprints that appear in directory documents. The names fingerprint and digest are used interchangeably in the specification but generally a fingerprint is a message digest (ie: SHA1) over the DER ASN.1 encoding of a public key. A digest is usually a message digest over a set of fields in a directory document. Digests always appear as a 40 character hex string: 0EA20CAA3CE696E561BC08B15E00106700E8F682 Fingerprints may either appear as a single hex string as above or sometimes in a more easily human-parsed spaced format: 1E0F 5874 2268 E82F C600 D81D 9064 07C5 7CC2 C3A7
