  76  *
  77  *     ALGNAME[VERSION?][-SUBNAME[VERSION?]?][-SIZE?][-MODE?]
  78  *
  79  *     VERSION is only present if there are multiple versions of
  80  *     an alg (MD2, MD4, MD5).  It may be omitted if there is only
  81  *     one version (if a subsequent version is released in the future,
  82  *     we can always change the canonical name, and add the old name
  83  *     as an alias).
  84  *
  85  *     SUBNAME may be present where we are combining multiple
  86  *     algorithms together, e.g. MD5-SHA1.
  87  *
  88  *     SIZE is only present if multiple versions of an algorithm exist
  89  *     with different sizes (e.g. AES-128-CBC, AES-256-CBC)
  90  *
  91  *     MODE is only present where applicable.
  92  *
  93  * We add diverse other names where applicable, such as the names that
  94  * NIST uses, or that are used for ASN.1 OBJECT IDENTIFIERs, or names
  95  * we have used historically.
  96  *
  97  * Algorithm names are case insensitive, but we use all caps in our "canonical"
  98  * names for consistency.
