SM4 is a 128-bit block cipher, currently established as a national standard (GB/T 32907-2016) of China. Multiple block cipher modes are supported. When using CBC or ECB mode, the PKCS#7 padding scheme is used.

This encrypt & decrypt tool complete implementation of SM4 cipher encryption/decryption with ECB, CBC, CFB, OFB, CTR block modes.

Type 7 Cipher, also known as Cisco Type 7 Encryption, is a method commonly used by Cisco networking devices to obfuscate sensitive information such as passwords in configuration files. While it's referred to as encryption, Type 7 is actually a weak form of encoding designed to obscure passwords rather than securely encrypting them.
