55 * For the algorithm names, we use the following formula for our primary

57 *
58 * ALGNAME[VERSION?][-SUBNAME[VERSION?]?][-SIZE?][-MODE?]
59 *
60 * VERSION is only present if there are multiple versions of
61 * an alg (MD2, MD4, MD5). It may be omitted if there is only
62 * one version (if a subsequent version is released in the future,
63 * we can always change the canonical name, and add the old name
64 * as an alias).
65 *
66 * SUBNAME may be present where we are combining multiple
67 * algorithms together, e.g. MD5-SHA1.
68 *
69 * SIZE is only present if multiple versions of an algorithm exist
70 * with different sizes (e.g. AES-128-CBC, AES-256-CBC)
71 *
72 * MODE is only present where applicable.
73 *
74 * We add diverse other names where applicable, such as the names that
75 * NIST uses, or that are used for ASN.1 OBJECT IDENTIFIERs, or names
76 * we have used historically.
77 *
78 * Algorithm names are case insensitive, but we use all caps in our "canonical"
79 * names for consistency.
