Cryptography Android application code samples / cipher collection for app users

cryptography's Issues

adfgvx cipher has fixed key

Note:

• Get key along with input
• create substitute table based on the key

Add hieroglyphic encoder

User requested.

Something like this https://www.youtube.com/watch?v=xuv7JRAmc7M

Implement automated test runs

Especially on pull requests?

Using Jenkins on my server maybe?

need to study this.

您好作者，希望开通支付宝移除广告功能

来自**的粉丝，倒霉的谷歌市场限制了我在**购买移除广告的消费。而我只能赞助0.99美元，我希望能有一个支付宝移除广告的办法。谢谢，同时我也希望能添加下菜单的中文翻译。

Add more methods from todays standards

• Ciphers
• Hashes
• Encoding methods.

Add short and simple descriptions to Readme what each category means

-> title

Start to use Github actions to run tests

With different java versions 8, 11, 15?

Add base58

https://tools.ietf.org/id/draft-msporny-base58-01.html

Write better tests

Should write more broader tests.

VIC cipher

Add VIC cipher: https://en.wikipedia.org/wiki/VIC_cipher

Part of the user comment: "...American scientists in the cold war Era and was pretty historically famous. It is probably the most sophisticated "by hand" cipher that can be done in reasonable time with only pen and paper...."

After developing/adding it here, will add to to Cryptography Android app.

Add ElsieFour LC4 cipher

Argon2 incomplete

The Argon2 implementation in the app seems incomplete.

Any plans to release an update with full parameter support, like already done for the SCrypt screen?

Elgamal Jenkins tests problem

Maybe Jenkins JDK version used with Ant here is causing: JCE cannot authenticate the provider BC for BC = BouncyCastle provider.

Add Webding encoder

User requested.

Need to investigate.

Add Pig Latin encoder

User requested.

Something like this https://www.youtube.com/watch?v=kAEPloVjP5I

Seems to be complicated set of rules.

Need to investigate.

EC (Elliptic Curve) ciphers

@SKR301 will implement these. @norkator will review and do tweaks.

Implement RLE (Run-Length Encoding)

Also to Cryptography application

Fix four square cipher

(has always been broken in Android app)

Add padding schemes

• PKCS#5
• PKCS#7

Note: "PKCS#5 padding is identical to PKCS#7 padding, except that it has only been defined for block ciphers that use a 64-bit (8-byte) block size. In practice the two can be used interchangeably."

• PKCS#10 ?? (https://datatracker.ietf.org/doc/html/rfc2986)

Implement ElGamal encryption

Also to Cryptography application

Khazad, Anubis not ciphered in right size blocks

Need to fix in some point. Leads to basically input bytes not being ciphered at all.

Add Wingding encoder

User requested.

https://en.wikipedia.org/wiki/Wingdings

Seems interesting.

"Mary Queen of Scots" cipher

Check, study and implement.

vernam cipher

User requested. Looks to be another name for One Time Pad cipher.

Label

CRYPT

AES return byte array to base64 change

@SKR301 #29

VIC further checks

• Try VIC implementation against some online tools.

If passing upper one, then:

• Implement VIC into Cryptography Android application.

Add Navajo substitution cipher

Mentioned by Android App user.
