Module rsa 

RSA encryption and signatures. RSA encryption and signatures.

Algorithms

• PKCS#1 v1.5 (RFC 8017): encryption and signature padding
• OAEP (RFC 8017): optimal asymmetric encryption padding
• RSASSA-PSS (RFC 8017 / PKCS#1 v2.2 §8.1): modern signature padding
• Key sizes: 512 (tests only), 1024 (tests), 2048, 3072, 4096 bits

Modules

• bigint: Big integer arithmetic (up to 4096-bit)
• rsa: RSA core key generation, raw encrypt/decrypt
• pkcs1: PKCS#1 v1.5 padding for encryption and signatures
• oaep: OAEP padding for encryption
• pss: RSASSA-PSS signatures (the modern RSA signature padding)

Modules

bigint

Big integer arithmetic for RSA (up to ~4096-bit numbers).

oaep

RSA-OAEP encryption padding (RFC 8017 / PKCS#1 v2.2 §7.1).

pkcs1

PKCS#1 v1.5 padding for encryption and signatures (RFC 8017).

pss

RSASSA-PSS signatures (RFC 8017 / PKCS#1 v2.2 §8.1).

rsa

RSA core operations (RFC 8017 / PKCS#1 v2.2): key generation, raw encrypt / decrypt with the Chinese Remainder Theorem (CRT).
