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

* ALGNAME[VERSION?][-SUBNAME[VERSION?]?][-SIZE?][-MODE?]

* VERSION is only present if there are multiple versions of
* an alg (MD2, MD4, MD5). It may be omitted if there is only
* one version (if a subsequent version is released in the future,
* we can always change the canonical name, and add the old name
* as an alias).
*
* SUBNAME may be present where we are combining multiple
* algorithms together, e.g. MD5-SHA1.
*
* SIZE is only present if multiple versions of an algorithm exist
* with different sizes (e.g. AES-128-CBC, AES-256-CBC)
*
* MODE is only present where applicable.
*
* We add diverse other names where applicable, such as the names that
* NIST uses, or that are used for ASN.1 OBJECT IDENTIFIERs, or names
* we have used historically.
*
* Algorithm names are case insensitive, but we use all caps in our "canonical"
* names for consistency.
