The RSA encryption C++ library can be used in applications and websites to encrypt files, strings, and byte arrays using public/private key pairs.

RSA C++ Library Features

• Public/private key generation.
• Encrypt with either public or private key.
• Decrypt with matching public or private key.
• Create digital signatures.
• Verify digital signatures.
• Encrypt and decrypt in-memory strings or byte arrays of any size.
• Encode encrypted output to Base64, Hex, Quoted-Printable, or URL-encoding
• Export public/private key pairs to XML.
• Import key pair from .snk file.
• Import public/private key pairs from XML.
• Import/Export only public-part or private-part of key pair.
• PKCS v1.5 padding for encryption and signatures.
• OAEP Padding Scheme for Encryption/Decryption
• RSASSA-PSS (RSA Signature Scheme with Appendix - Probabilistic Signature Scheme)
• Create/verify signatures with little-endian or big-endian byte ordering.
• Supports key sizes ranging from 512 bits to 4096 bits.
