Extract text from SHA-1 checksum files (SHA1)
To convert SHA1 checksum files to another format, you need sha1sum or other Data software.
To convert other file formats to the "Checksum & Verification" file type, you need software like sha1sum or a similar tool.
The .SHA1 file extension serves two entirely unrelated purposes. Primarily, it is a plain text file containing a 160-bit cryptographic hash generated by the Secure Hash Algorithm 1. These files are used by utilities like sha1sum to verify data integrity and ensure downloaded files are not corrupted.
Users often misunderstand .SHA1 checksum files, assuming they contain the actual downloaded movie, game, or software archive. A checksum file is typically only a few bytes in size and cannot be "converted" into an ISO, MP4, or ZIP file. The primary disadvantage is simply user confusion. To easily read the hash, the best target format is TXT.
Alternatively, the .SHA1 extension was used by Monolith Productions for the video game F.E.A.R.. In this context, it is a disguised RIFF/AVI video file used for game assets. The developers deliberately changed the extension to prevent players from casually watching cutscenes outside the game engine. To play these, you can rename them to AVI and use VLC media player, or convert them to modern MP4 files.
Because of this dual nature, standard online converters usually fail. They either attempt to process a text file as media or fail to recognize a disguised video asset. We can inspect the file, show the raw hash text, or detect the underlying media format so you can convert it if supported.
Convert.Guru analyzes your SHA1 file, detects the exact format, and lets you read the text inside.
Users also converted SHAI, SHA, TXT, JPG, BIN, PNG, TEXT, MD5, SHA256 and HEX files.
If you want to convert SHA1 file to TEXT, MD5, SHA256, HEX, BASE64, BIN, ENC, CRYPT, AES, DES, RSA or PGP, you can use sha1sum or similar software from the "Cryptographic Hash Verification" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or HEX files to SHA1, try sha1sum or another comparable tool in the "Cryptographic Hash Verification" 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 SHA1 converter.
