Python Flask routes












0














I'm new to programming and in back-end. Right now I'm trying to learn flask, so I wrote a very simple website that currently encrypts and decrypts the message using RSA and DES.



I feel like my app.py file is just bad and should do it much better. I mean, there're a lot of repeating code like this:



@app.route('/rsa_encrypt', methods=['GET', 'POST'])
def RSA_enc():
global get_form
if request.method == "GET":
get_form = True
return render_template('rsa_encrypt.html', gf=get_form)
else:
get_form = False
rsa = RSA(request.form.get('pt'), p=request.form.get('p'),
q=request.form.get('q'), e=request.form.get('e'))
return render_template('rsa_encrypt.html', gf=get_form, rsa=rsa, gspn=gspn)


I tried to write some decorators for those routes, but they didn't work well.



Can you take a look and tell me what should I do better? It works but I think not as well as it should.



app.py



from flask import Flask, render_template, request, url_for, jsonify
from ciphers import RSA, DES
from prime import generate_semiprime_number as gspn

app = Flask(__name__)
get_form = None

@app.route('/')
def index():
return render_template('index.html')

@app.route('/rsa_encrypt', methods=['GET', 'POST'])
def RSA_enc():
global get_form
if request.method == "GET":
get_form = True
return render_template('rsa_encrypt.html', gf=get_form)
else:
get_form = False
rsa = RSA(request.form.get('pt'), p=request.form.get('p'),
q=request.form.get('q'), e=request.form.get('e'))
return render_template('rsa_encrypt.html', gf=get_form, rsa=rsa, gspn=gspn)

@app.route('/rsa_decrypt', methods=['GET', 'POST'])
def RSA_dec():
global get_form
if request.method == "GET":
get_form = True
return render_template('rsa_decrypt.html', gf=get_form)

rsa = RSA(ciphertext=ct, p=request.form.get('p'),
q=request.form.get('q'), e=request.form.get('e'))
return render_template('rsa_decrypt.html', gf=get_form, rsa=rsa)

@app.route('/des_encrypt', methods=['GET', 'POST'])
def DES_enc():
