SHA encryption is a term that refers to a family of cryptographic hash functions that are used to verify the integrity and authenticity of data. A hash function is a mathematical function that takes an input and produces a fixed-length output, called a hash or a digest, that is unique for each input. SHA encryption can be used to generate digital signatures, checksums, passwords and other security applications.

​PBKDF2 Encryption is a specific type of Password-Based Key Derivation Function Encryption (PBKDF Encryption) that uses a pseudorandom function, such as hash-based message authentication code (HMAC), to generate a derived key from a password or a passphrase

Symmetric Encrypt & Decrypt Online Tool is a web online tool that allows you to encrypt and decrypt text using symmetric encryption algorithms such as AES, Triple DES and DES. Symmetric encryption is widely used for data protection, authentication and digital signatures.

TEA (Tiny Encryption Algorithm) is a block cipher notable for its simplicity of description and implementation, typically a few lines of code. TEA Encrypt & Decrypt is a free online tool that for Tiny Encryption Algorithm Encrypt & Decrypt.
