不能在Docker Alpine Linux 3.3中使用OpenSSL 1.0.2g和Python 2.7"pip安装加密"

Question

解决了哇,这些家伙很快......基本上就是这个https://github.com/pyca/cryptography/issues/2750事实证明,openssl的安全更新已经发布(DROWN Attack),并且该更新包含了一个意想不到的功能签名更改导致不兼容,所以这对我来说只是运气不好.

我需要pip install cryptography在运行Alpine Linux的Docker容器中使用.实际上,它是另一个模块,service_identity但问题在于cryptography模块,它是一个依赖项.

我有以下Dockerfile

FROM alpine:3.3

RUN apk --update add build-base libffi-dev openssl-dev python-dev py-pip
RUN pip install cryptography

失败,出现以下错误

generating cffi module 'build/temp.linux-x86_64-2.7/_openssl.c'

      ^

openssl 1.0.2g于2016-03-01(昨天)发布,alpine软件包已经更新到该版本.它可以与此相关吗？

我该如何解决这个问题？也许我可以设置一些环境变量？

更新我已经检查GitHub库OpenSSL的,而事实上BIO *BIO_new_mem_buf(void *buf, int len)的openssl/bio.h得到了改变,以BIO *BIO_new_mem_buf(const void *buf, int len)在1.0.2f期间1.0.2g转变(在搜索"BIO_new_mem_buf" https://github.com/openssl/openssl/compare/ OpenSSL_1_0_2f ... OpenSSL_1_0_2g).我不知道这openssl/asn1.h是从哪里来的,这是导入过时的版本openssl/bio.h,因为它看起来不像openssl repo中的那个.有任何想法吗？

好的,我看到一些人已经在努力了:https: //github.com/pyca/cryptography/issues/2750

仍然在Alpine 3.7中遇到加密问题== 2.1.4

解决方案：

apk add --no-cache libressl-dev musl-dev libffi-dev

范例：

RUN apk add --no-cache \
        libressl-dev \
        musl-dev \
        libffi-dev && \
    pip install --no-cache-dir cryptography==2.1.4 && \
    apk del libressl-dev \
        musl-dev \
        libffi-dev

应该解决。

参考：

https://github.com/pyca/cryptography/blob/master/docs/installation.rst

如果链接过期：

$ pip install cryptography 如果您使用的是Alpine或只是想自己编译，则加密需要编译器，Python的标头（如果您未使用pypy）以及系统上可用的OpenSSL和libffi库的标头。

高山的

如果您使用的是Python 2，请用python-dev替换python3-dev。

$ sudo apk add gcc musl-dev python3-dev libffi-dev openssl-dev

如果您遇到错误，则openssl-dev可能必须使用libressl-dev。

Answer 2

如果由于 Rust 版本而失败，则建议在密码学的文档中执行以下操作：

The Rust available by default in Alpine < 3.12 is older than the 
minimum supported version. See the Rust installation instructions
 for information about installing a newer Rust.

The Rust available by default in Alpine < 3.12 is older than the 
minimum supported version. See the Rust installation instructions
 for information about installing a newer Rust.

就我而言，python3.8-alpine，添加已cargo解决。
