# Adapted from the homepage: |
||||
s.description = <<-DESC |
||||
BoringSSL is a fork of OpenSSL that is designed to meet Google's needs. |
||||
|
||||
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. |
||||
We don't recommend that third parties depend upon it. Doing so is likely to be frustrating |
||||
because there are no guarantees of API stability. Only the latest version of this pod is |
||||
supported, and every new version is a new major version. |
||||
|
||||
We update Google libraries and programs that use BoringSSL as needed when deciding to make API |
||||
changes. This allows us to mostly avoid compromises in the name of compatibility. It works for |
||||
us, but it may not work for you. |
||||
|
||||
As a Cocoapods pod, it has the advantage over OpenSSL's pods that the library doesn't need to |
||||
be precompiled. This eliminates the 10 - 20 minutes of wait the first time a user does "pod |
||||
install", lets it be used as a dynamic framework (pending solution of Cocoapods' issue #4605), |
||||
and works with bitcode automatically. It's also thought to be smaller than OpenSSL (which takes |
||||
1MB - 2MB per ARM architecture), but we don't have specific numbers yet. |
||||
|
||||
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built |
||||
up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's |
||||
product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved |
||||
in maintaining all these patches in multiple places was growing steadily. |
||||
|
||||
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the |
||||
NDK) and a number of other apps/programs. |

# allow any header to be listed outside the `header_mappings_dir` (even though doing so works in |
||||
# practice). Because we need our `header_mappings_dir` to be `include/openssl/` for the reason |
||||
# mentioned above, we work around the linter limitation by dividing the pod into two subspecs, one |

# for public headers and the other for implementation. Each gets its own `header_mappings_dir`, |
