Constructor Detail

Trustworthiness

public Trustworthiness(int amount,
                       int depth)

Method Detail

getAmount

public int getAmount()

Get the trust amount. This value means how confident the issuer of the signature is in validity of the binding.

Returns:

trust amount

getDepth

public int getDepth()

Get the depth of the trust signature. This value controls, whether the certificate can act as a trusted introducer.

Returns:

depth

isNotTrusted

public boolean isNotTrusted()

Returns true, if the trust amount is equal to 0. This means the key is not trusted. Otherwise return false

Returns:

true if untrusted

isMarginallyTrusted

public boolean isMarginallyTrusted()

Return true if the certificate is at least marginally trusted. That is the case, if the trust amount is greater than 0.

Returns:

true if the cert is at least marginally trusted

isFullyTrusted

public boolean isFullyTrusted()

Return true if the certificate is fully trusted. That is the case if the trust amount is greater than or equal to 120.

Returns:

true if the cert is fully trusted

isIntroducer

public boolean isIntroducer()

Return true, if the cert is an introducer. That is the case if the depth is greater 0.

Returns:

true if introducer

canIntroduce

public boolean canIntroduce(int otherDepth)

Return true, if the certified cert can introduce certificates with trust depth of

otherDepth

.

Parameters:

otherDepth - other certifications trust depth

Returns:

true if the cert can introduce the other

canIntroduce

public boolean canIntroduce(Trustworthiness other)

Return true, if the certified cert can introduce certificates with the given

other

trust depth.

Parameters:

other - other certificates trust depth

Returns:

true if the cert can introduce the other

fullyTrusted

public static Trustworthiness.Builder fullyTrusted()

This means that we are fully convinced of the trustworthiness of the key.

Returns:

builder

marginallyTrusted

public static Trustworthiness.Builder marginallyTrusted()

This means that we are marginally (partially) convinced of the trustworthiness of the key.

Returns:

builder

untrusted

public static Trustworthiness.Builder untrusted()

This means that we do not trust the key. Can be used to overwrite previous trust.

Returns:

builder
