77 algorithms: the "high level" APIs (such as the C<EVP> APIs) and the "low level"
78 APIs. The high level APIs are typically designed to work across all algorithm
79 types. The "low level" APIs are targeted at a specific algorithm implementation.
83 On the other hand, to do AES encryption using the low level APIs you would have
