Convert ENC to TXT

A receiving program, device, or data-import workflow may accept only a readable .txt file while the supplied .enc file is encrypted, encoded, or proprietary. The required process is determined by the program that created the file; changing .enc to .txt changes only the name.

What the ENC format is

ENC is not one standardized file format. The extension may identify an encrypted file created with OpenSSL, GnuPG, or an application-specific security tool; a Base64-encoded export; or proprietary records, configuration data, or media. The extension alone cannot identify the file structure, encryption method, original content type, or required password.

Ask the sender which application or device created the file, whether it is encrypted, and which password, key, cipher, or export settings were used. On macOS or Linux, file input.enc can identify some formats. For a non-confidential file, strings input.enc or a hex editor may reveal readable clues, but encrypted data normally has no useful text or recognizable signature.

What the TXT format is

.txt contains unformatted characters without page layout, images, formulas, or application-specific styling. Plain text works with command-line tools, logs, data imports, search systems, email attachments, and long-term archives, and is usually smaller than a formatted document.

Choose UTF-8 when exporting text containing accented or non-Latin characters. Plain text cannot preserve tables, images, fonts, rich formatting, embedded metadata, or the structure of non-text files.

How to perform the conversion

Decrypt an OpenSSL file

Use OpenSSL when the creator confirms that the file was produced with its enc command. The decryption options must match the original cipher, password handling, digest, salt behavior, and key-derivation method. For a file created with AES-256-CBC and PBKDF2, a typical command is:

openssl enc -d -aes-256-cbc -pbkdf2 -in input.enc -out output.txt

OpenSSL prompts for the password. This command does not work for every OpenSSL file: older files may omit -pbkdf2 or use different options. Obtain the original command or settings instead of guessing. A successful decryption can produce a PDF, image, archive, or database rather than text; use the correct extension for that output.

Decrypt a GnuPG file

Install GnuPG; on Windows, Gpg4win includes the Kleopatra graphical interface. For a GnuPG file, run:

gpg --output output.txt --decrypt input.enc

GnuPG requests the passphrase or uses the matching private key. In Kleopatra, select the file, choose Decrypt/Verify, provide the credentials, and save the result as .txt only if the decrypted content is plain text.

Decode a Base64 file

Base64 is encoding, not encryption. Decode it only when the sender confirms that the ENC file contains Base64 text. On Linux, use:

base64 --decode input.enc > output.txt

On macOS, use:

base64 -D input.enc > output.txt

On Windows, use:

certutil -decode input.enc output.txt

Decoding restores the original bytes. The result is a valid text file only when those bytes were originally text; otherwise, identify and retain the original file type.

Export from the creating application

For proprietary ENC files, open the file in the application or device that generated it and use a command such as File → Export → Text, File → Save as → TXT, or Export data → CSV/TXT. Vendor software is the reliable option when the file contains application records, device data, or proprietary encryption.

If the application exports CSV, open the CSV in a text editor or spreadsheet and save it as UTF-8 plain text. Check the delimiter, quoting, decimal format, and line endings before importing the result into another system.

When renaming is sufficient

Some programs use .enc for ordinary text with a nonstandard extension. Open a copy in a plain-text editor, or inspect a non-confidential copy with file. If the content is already readable text and the receiving program requires .txt, rename the copy from input.enc to input.txt. This does not decrypt, decode, or transform the data.

Online converters and compatibility limits

CloudConvert and Zamzar are reputable general-purpose services, but an arbitrary ENC file is not automatically supported by either service. Use an online converter only when its upload page explicitly lists the particular ENC variant and TXT as supported formats, and only for non-sensitive data. A converter cannot decrypt a file without the required password or key, and uploading confidential content transfers it to a third party.

For private files, use OpenSSL, GnuPG/Gpg4win, or the original desktop application. After processing, inspect the result with file output.txt and a plain-text editor. Verify character encoding, line endings, delimiters, and missing metadata, and retain the original ENC file because an incorrect decryption or export may not be reversible.
