chibi-crypto

Chibi Scheme's crypto library

Module: (chibi crypto md5)

md5

md5 srcprocedure

Returns the md5 checksum of src as a lowercase hex-string. src can be any of a string (interpreted as utf8), a bytevector, or a binary input port.

Module: (chibi crypto sha2)

sha-224

sha-224 srcprocedure

Computes SHA-224 digest of the src which can be a string, a bytevector, or a binary input port. Returns a hexadecimal string (in lowercase).

sha-256

sha-256 srcprocedure

Computes SHA-256 digest of the src which can be a string, a bytevector, or a binary input port. Returns a hexadecimal string (in lowercase).

Module: (chibi crypto rsa)

Please note: this library should not be considered cryptographically secure because:

rsa-key-gen-from-primes

rsa-key-gen-from-primes bit-length p q #!optional exponentprocedure

Generate RSA key pair record with bit-length using primes p, q, and optional exponent.

rsa-key-gen

rsa-key-gen #!optional (bit-length 128)procedure

Generate an RSA key pair record with bit-length, which defaults to 128.

rsa-pub-key

rsa-pub-key priv-keyprocedure

Returns a copy of the given key with the private key, if any,removed.

pkcs1-pad

pkcs1-pad bvprocedure

Undocumented

pkcs1-unpad

pkcs1-unpad bvprocedure

Undocumented

rsa-encrypt

rsa-encrypt pub-key msgprocedure

Encrypts msg for the given public key pub-key. msg may be an integer or bytevector, in which case the result is of the same type, or a string, in which case the string is first coerced to a utf8 encoded bytevector.

rsa-decrypt

rsa-decrypt priv-key cipherprocedure

Decrypts cipher using the given private key priv-key. cipher may be an integer or bytevector, in which case the result is of the same type, or a string, in which case the string is first coerced to a utf8 encoded bytevector.

rsa-sign

rsa-sign priv-key msgprocedure

Signs msg using the given private key priv-key.

rsa-verify

rsa-verify pub-key sigprocedure

Returns the verified (decrypted) message for the signature sig.

rsa-verify?

rsa-verify? pub-key msg sigprocedure

Returns true iff sig is a valid signature of msg for the given public key pub-key.
