Extract text from encrypted files (EOC)
To convert EOC encrypted files to another format, you need EncryptOnClick or other Encoded software.
To convert other file formats to the "Encrypted Ransomware Archive" file type, you need software like EncryptOnClick or a similar tool.
The .eoc file extension is most notoriously associated with the Nemucod ransomware, which maliciously encrypts user files into locked ZIP archives. In legitimate enterprise environments, it functions as an electronic commerce data file for the 3M Electronic Ordering Center, storing business data in raw UTF-16 (LE) text. A smaller percentage of these files are secure archives generated by EncryptOnClick, a security utility developed by 2BrightSparks.
Converting an .eoc file is incredibly challenging. If the file is locked by ransomware or EncryptOnClick, standard online converters will completely fail. The underlying data is obfuscated by strong encryption algorithms, meaning that without the specific decryption key or password, the file remains an inaccessible data block. Users face severe limitations because they cannot open, edit, or view the contents. The 3M variant, while unencrypted, relies on a highly proprietary e-commerce schema that most software simply cannot parse.
If you possess a legitimate 3M file, extracting the data to TXT or CSV is the best conversion target, though proprietary formatting will be lost. For EncryptOnClick files, the target is the original unencrypted file (often a ZIP or DOCX).
Because this file format is heavily restricted, closed, and frequently encrypted, only the original decryption tool or the proprietary 3M software can properly read the data. Our deep analysis can detect whether your file contains a supported underlying UTF-16 text structure or if it is a heavily encrypted archive.
Convert.Guru analyzes your EOC file, detects the exact format, and lets you read the text inside.
Users also converted SDU, SGA and WZ files.
If you want to convert EOC file to BASE64, HEX, BIN, ENC, CRYPT, AES, DES, RSA, PGP, GPG, ASC or KEY, you can use EncryptOnClick or similar software from the "Encrypted File Archive" 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 EOC, try EncryptOnClick or another comparable tool in the "Encrypted File Archive" 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 EOC converter.
