gnutls_base64_encode2 - Linux

Overview

gnutls_base64_encode2 is a command-line utility for encoding arbitrary binary data into Base64 format. Base64 encoding converts binary data into a string of ASCII characters, making it suitable for transmission over channels that can only handle text.

Syntax

gnutls_base64_encode2 [options]

Options/Flags

• -i, –input [FILE]
  Specify the input file containing the binary data to be encoded.
• -o, –output [FILE]
  Specify the output file where the encoded data should be saved.
• -d, –decode
  Decode the input data from Base64 format to binary.
• -l, –line-length [NUM]
  Set the maximum length of output lines.
• -h, –help
  Print help and usage information.

Examples

Encode a file:

gnutls_base64_encode2 -i image.png -o encoded.txt

Decode a file:

gnutls_base64_encode2 -d -i encoded.txt -o decoded.png

Common Issues

• Encoding errors:
  Verify that the input file contains valid binary data.
• Decoding errors:
  Ensure that the input file contains properly encoded Base64 data.

Integration

gnutls_base64_encode2 can be used as part of scripts or command chains for tasks such as:

• Secure data transmission: Encode emails or other sensitive data for secure transfer over text channels.
• Configuration files: Encode binary configuration data into text form for easy storage in configuration files.
