The OpenSSL library enforces security levels to control the minimum acceptable
level of security for cryptographic operations. OpenSSL's security levels range
from 0 to 5, with each level imposing stricter security requirements. The default
security level is 1, which is generally suitable for most modern applications.
security level is 2, which is generally suitable for most modern applications.
However, some legacy features and protocols, such as TLSv1, require a lower
security level (`SECLEVEL=0`) to function properly. For more detailed information,
please refer to the [OpenSSL documentation on security levels][].
