About DER files

DER (Distinguished Encoding Rules) is a binary format for encoding data objects in a structured way. It is commonly used to store digital certificates and keys in a secure format. It is not a widely used file format and is not easily readable by humans. It is also not supported by many applications.

The most common way to convert a DER file is to use a program such as OpenSSL or GnuPG. These programs can convert DER files to formats such as PEM (Privacy Enhanced Mail), PFX (Personal Information Exchange), and P7B (PKCS #7 Certificate).

When converting a DER file, it is important to consider the security of the data. DER files are often used to store sensitive data, and it is important to ensure that the converted file is secure. Additionally, DER files can be difficult to convert due to their binary format, and the process can be time-consuming and complicated.

For these reasons, it is often easier to use an online service such as Convert.Guru to convert DER files. Convert.Guru offers a free and easy-to-use website for converting DER files to other formats.

The DER Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DER converter.
