Click the "Select File" button above, and choose your PK8 file.
You’ll see a preview, if available.

Convert PK8 to another file type
To convert PK8 Private keys to another format, you need OpenSSL or other Encoded software.
Convert a file to PK8
To convert other file formats to the "PKCS#8 Private Key" file type, you need software like OpenSSL or a similar tool.
About PK8 files
The .PK8 file format primarily functions as a PKCS#8 Private Key file, standardizing the storage of private key information under the RSA Security cryptography standards. A secondary, completely unrelated use is for Generation 8 Pokémon Save Files created by Nintendo games. The primary disadvantage of the .PK8 cryptographic format is its inherent strictness; it often stores sensitive data in a binary or encrypted state that standard text editors cannot read. Server administrators frequently need to convert .PK8 files to Base64-encoded PEM or KEY formats to configure web servers like Apache or Nginx. Because it is a highly specialized format, standard online tools fail to parse the underlying cryptography without decryption passwords. Furthermore, uploading active private keys to the internet is a massive security risk. If our analysis detects a supported underlying structure, viewing or conversion may still be possible without compromising secure data.
Convert.Guru analyzes your PK8 file, detects the exact format, and lets you read the text inside.
If you want to convert PK8 file to PEM, KEY, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF or DAT, you can use OpenSSL or similar software from the "Cryptographic Private Key Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to PK8, try OpenSSL or another comparable tool in the "Cryptographic Private Key Storage" category.
The PK8 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 PK8 converter.
