E-Media

Graphical application for extracting, and displaying PNG images metadata, calculating and displaying fft. Images can also be anonymized and encrypted using RSA algorithm.

Supported chunks

Every valid chunk will be parsed but not every chunk's data is being parsed.

Supported chunks for data parsing:

• IHDR: image header
• PLTE: palette: a list of colors
• IDAT: image data
• IEND: end of file
• sBIT: significant bits: color-accuracy of the source data
• gAMA: image gamma
• sRGB: standard RGB colour space
• pHYs: physical pixel dimensions
• tEXt: textual data
• iTXt: international textual data
• zTXt: compressed textual data
• iCCP: embedded ICC profile
• tIME: last modification time
• bKGD: background colour
• cHRM: primary chromaticities and white point
• hIST: image histogram
• sPLT: suggested palette
• eXIf: exchangeable image file format data

RSA

The app uses 2 diffrent RSA implementations:

1. Custom one implemented by us
2. Using PyCryptodome library (currently only key generation works)
