# Result Table The table hereafter is the result of all benchmarks *with our development environment*. It is given to help you to select the appropriate algorithms for your application. **The use of the algorithm** `ECDH-ES` **with curves** `P-256`**,** `P-384` **or** `P-521` **is not recommended with PHP7.1 or 7.2**. The cryptographic operations with those curves are done using a pure PHP function and hence very slow. The use of the RSA algorithms with a very long key (more that 4096 bits) is quite slow, but offers a good protection. The PBES2\* algorithms are quite slow, but also offer a good protection (see ). Default salt size (512 bits) and iterations (4096) and custom values (256/1024) used for the tests. Those values can be configured if needed. | subject | groups | mean | | --------------------- | -------------------------------- |
