Extract text from Kerberos keytab files (KEYTAB)
To convert KEYTAB keytab files to another format, you need MIT Kerberos or other System software.
To convert other file formats to the "Authentication Credential File" file type, you need software like MIT Kerberos or a similar tool.
A .keytab (Key Table) file is a critical system file used by the Kerberos Authentication Protocol to store pairs of Kerberos principals and encrypted keys. It allows automated scripts, background services, and servers to log into Kerberos realms (such as Microsoft Active Directory or MIT Kerberos) without requiring human interaction or manual password entry.
This format has significant disadvantages for average users. It is a strictly structured, proprietary binary file. Opening a .keytab in a standard text editor will display garbled text, and saving it will permanently corrupt the file. Furthermore, the file contains highly sensitive security credentials; mishandling or misconfiguring it can severely compromise network security.
Users often need to convert or inspect .keytab files to extract principal names, audit encryption types (such as AES256-CTS-HMAC-SHA1-96), or encode the file to Base64 for inclusion in CI/CD pipeline variables. Standard online converters fail because this is a closed cryptographic format. Standard manipulation requires specialized command-line tools like ktutil on Unix/Linux or ktpass on Windows.
Because it is a compiled binary format, it is extremely difficult to read or convert without the original environment. If our analysis detects a supported underlying or embedded format, viewing or metadata extraction may still be possible.
Convert.Guru analyzes your KEYTAB file, detects the exact format, and lets you read the text inside.
Users also converted RPMSG, SPRITE, SB2 and AIA files.
If you want to convert KEYTAB file to SYS, DLL, EXE, DRV, VXD, 386, COM, BAT, CMD, SCR, PIF or LNK, you can use MIT Kerberos or similar software from the "Automated Kerberos Authentication" category. In the File menu, look for Save As… or Export….
To convert MSI, EXE, REG, MST, LNK, CAB, CAT, DRV, INF, SYS, MSU or DLL files to KEYTAB, try MIT Kerberos or another comparable tool in the "Automated Kerberos Authentication" category.
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 KEYTAB converter.
