**Cryptopals Crypto Challenges**

These are my attempts to solve the Cryptopals challenges using PHP.

**Crypto Challenge Set 1: Basics**

- [x] Convert hex to base64

- [x] Fixed XOR

- [x] Single-byte XOR cipher

- [x] Detect single-character XOR

- [x] Implement repeating-key XOR

- [x] Break repeating-key XOR

- [x] AES in ECB mode

- [x] Detect AES in ECB mode

**Crypto Challenge Set 2: Block Crypto**

- [x] Implement PKCS#7 padding

- [x] Implement CBC mode

- [x] An ECB/CBC detection oracle

- [ ] Byte-at-a-time ECB decryption (Simple)

- [ ] ECB cut-and-paste

- [ ] Byte-at-a-time ECB decryption (Harder)

- [ ] PKCS#7 padding validation

- [ ] CBC bitflipping attacks
