SSL 證書可以在文件的單行上（無換行符）嗎？

SSL 證書預設在 67 個字元後有換行符。我正在嘗試使用 Chef 創建 SSL 證書文件。本質上，我想從一個字元串變數創建整個證書文件，而不需要任何換行符。我已經嘗試了幾次無濟於事（Apache抱怨無法找到證書）。

我不明白為什麼 SSL 證書中的換行是必要的。如果可以在文件中沒有任何換行符的證書，有什麼想法嗎？

不，如果沒有換行符，證書將無法正確處理 - 軟體將無法解析它。

如果您嘗試將其傳遞到字元串中，為什麼不將它們包含在其中？( \n)

我發現這個腳本很少這樣做。

awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}'  ca.pem

這將採用多行的標準 PEM 文件，將“隱藏的”換行符替換為\n，並將輸出列印為單行。

例如，這將使以下 PEM 文件…
