74 =head3 Low Level APIs
76 OpenSSL has historically provided two sets of APIs for invoking cryptographic
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.
80 For example, the EVP APIs provide the functions L<EVP_EncryptInit_ex(3)>,
83 On the other hand, to do AES encryption using the low level APIs you would have
86 Use of the low level APIs has been informally discouraged by the OpenSSL
88 formal. All such low level APIs have been deprecated. You may still use them in
90 compilation (dependent on compiler support for this). Deprecated APIs may be

99 the EVP APIs are now considered legacy and their use is strongly discouraged.
104 Applications using the EVP APIs to access these algorithms should instead use
