FortisRsaPrivateKey class RSA

An RSA private key used for decryption.

Pure data container wrapping PointyCastle's RSAPrivateKey. Serialization is available via toPem, toDer, and toDerBase64; import via fromPem, fromDer, and fromDerBase64. To decrypt data, build an RsaDecrypter via RsaBuilder.

⚠️ Handle with care — treat the output of toPem / toDer / toDerBase64 as a secret.

Example:

final pair = await Fortis.rsa().generateKeyPair();
final pem = pair.privateKey.toPem();
final restored = FortisRsaPrivateKey.fromPem(pem);

See also:

• RsaDecrypter, which consumes this key.
• FortisRsaPublicKey, the matching half of the pair.
• RsaPrivateKeyFormat, the PKCS#8 / PKCS#1 choice every to* / from* member takes.

Constructors

FortisRsaPrivateKey(RSAPrivateKey key)

Creates a FortisRsaPrivateKey from a raw PointyCastle RSAPrivateKey.

const

FortisRsaPrivateKey.fromDer(Uint8List der, {RsaPrivateKeyFormat format = RsaPrivateKeyFormat.pkcs8})

Imports a private key from DER bytes (binary ASN.1).

factory

FortisRsaPrivateKey.fromDerBase64(String base64, {RsaPrivateKeyFormat format = RsaPrivateKeyFormat.pkcs8})

Imports a private key from a Base64-encoded DER string.

factory

FortisRsaPrivateKey.fromPem(String pem, {RsaPrivateKeyFormat format = RsaPrivateKeyFormat.pkcs8})

Imports a private key from a PEM string.
