Extract text from Bizkaia tax backups (BFA)
To convert BFA tax backups to another format, you need Bizkaia Tax Portal or other Encoded software.
To convert other file formats to the "Encrypted Archive File" file type, you need software like Bizkaia Tax Portal or a similar tool.
The .BFA file format primarily represents three completely distinct data types: a maliciously encrypted file generated by Locky ransomware, a regional tax declaration backup from the Diputación Foral de Bizkaia, or a Blowfish encrypted archive. When dealing with Bizkaia tax backups, the file is essentially a standard ZIP container holding tax declaration data. The main disadvantage of using the official tax portal software is its limited platform compatibility. Users often need to extract these files to access the underlying XML or PDF documents for their own records.
Conversely, if your .BFA file is the result of a Locky ransomware infection or a secure Blowfish encryption utility like BestCrypt, the file is tightly locked by an cryptographic algorithm. The major disadvantage here is that without the correct private decryption key, the original data is entirely inaccessible. Standard online converters fail to process these files because they cannot bypass AES or Blowfish encryption protocols. This file format is notoriously difficult to open or convert because only the original encrypting software (or a verified malware decryptor) can properly decode the data.
Just drag and drop your file to identify the format, view it, and convert it when possible. While standard converters hit a wall with encryption, convert.guru can safely inspect the file's binary header. If our analysis detects a supported underlying or embedded format - such as the ZIP structure of a Spanish tax backup - viewing or conversion to ZIP may still be possible. For ransomware variants, identifying the exact malware signature is the critical first step toward finding a public decryption tool.
Convert.Guru analyzes your BFA file, detects the exact format, and lets you read the text inside.
Users also converted BCA, BTOS and TAD files.
If you want to convert BFA file to BASE64, HEX, BIN, ENC, CRYPT, AES, DES, RSA, PGP, GPG, ASC or KEY, you can use Bizkaia Tax Portal or similar software from the "Encrypted Data Storage" 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 BFA, try Bizkaia Tax Portal or another comparable tool in the "Encrypted Data Storage" 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 BFA converter.
