Telive osmo-tetra-sq5bpf: An Experimental TETRA Decoder that Enables Voice Decryption (If You Have the Key)
嗯，用户让我帮忙总结一篇文章，控制在100字以内，而且不需要特定的开头。首先，我需要仔细阅读文章内容，理解主要信息。
文章讲的是Jacek/SQ5BPF发布了一个修改版的Telive TETRA解码器，适用于Linux。这个修改允许用户在有解密密钥的情况下收听TEAx加密的语音信号。通常情况下，如果没有密钥是无法收听加密信号的。此外，因为TEA1加密在2023年被发现有后门而被破解，所以这个解码器还支持直接使用32位短密钥，并且可以通过teatime软件自动恢复。虽然TEA1正在被淘汰，但很多系统还在使用。软件是为高级用户设计的，需要自行编译和运行，文档很少，但有一个博客和RadioReference的帖子提供更多信息。
接下来，我需要把这些要点浓缩到100字以内。重点包括：Jacek/SQ5BPF发布修改版解码器、支持TEAx加密、需密钥、TEA1被破解、支持短密钥、软件为高级用户设计、资源有限。
然后组织语言，确保简洁明了。比如：“Jacek/SQ5BPF发布了Linux版Telive TETRA解码器的修改版本，支持TEAx加密语音信号的收听（需密钥）。由于TEA1加密在2023年因后门被破解，该版本还支持直接使用32位短密钥，并可通过teatime软件自动恢复。此工具专为高级用户设计。” 这样刚好控制在100字左右。
最后检查一下是否遗漏了关键信息，并确保语言流畅自然。

Thank you to Jacek / SQ5BPF for letting us know that he's recently released a modified version of the Telive TETRA decoder for Linux. The modification allows the user to listen to TEAx-encrypted voice signals if they have the decryption key. Typically, if a TETRA signal is encrypted, there is no way to listen to it, unless you have obtained the decryption key from the network operator, or extracted it from TETRA keyloader hardware.
But because the TEA1 encryption was broken due to a backdoor being discovered in 2023, he has also added support for using the 32-bit short key directly, which can be automatically recovered from TETRA traffic using his other software called teatime. TEA1 encryption is being phased out, but many deployments still use it.
The software is designed for advanced users to compile and run, so very little documentation is provided. However, there is a blog post here that explains the overall steps. Some additional information can be found on SQ 5BPF's RadioReference post here.
